For all the designations for different closes, namely F close, ! close, # close, email close etc, I've never come across a single thread or video yet that has even mentioned, let alone given much legitimacy it seems, to closing a social networking invite or IM screen name. Which is why I present the

close. A

close is essentially being permitted to befriend her on a social networking site or instant messaging service by being given her name or screen name.
The validity of starting, amplifying, and continuing a relationship over facebook, myspace, or AIM is drastically underrated but it does offer real benefits to people of all levels.
1. It's a simple, 'low cost' close with not much risk for rejection which is great for everyone from newbie afc's to even mpuas at times. It's often perceived that there's little to no investment for the girl to simply give her name out to make new friends seeing as her first name was most likely already given upon introduction Plus everyone likes to make friends, even if it is online, so its a high probability close. It's literaly as easy as just saying 'Hey, I have to get going but I think we'd be good facebook/AIM/myspace friends...How do you spell your name again?" Even better, after a successful hook, tell the girl to facebook you...it expresses a time and effort investment to get to know you better on her part...a good sign.
2. It's arguably the easiest and most calculated game you can run to ensure as high of an attraction/intrigue return as possible. Much like text game, AIM or facebook messaging (which has either PM or IM capabilities now), it can allow you to express youself in the best possible way (cocky/funny, negs, building comfort, etc) you can which, even in the worst case scenario, will both get your foot in the door and raise intrigue with clever responses to the girl but also reinforce possible openers, routines, or other topics into your unconscious that will indefinatly be useful in sarging at a later date.
3. It's really easy to elevate from a solely facebook/IM status to an invitation to go out on a day 2 or simply a number exchange so that you can give her a call to hang out/text her someday. Assuming you've had a positive initial interaction before which you

closed, which I'm not sure why you'd feel compelled to chase her if you didn't, she'll be apt to continuing the interation and tell you more about herself (use bf destroyers appropriately haha) b/c remember girls are emotional beings and are preprogrammed to respond intensely to such drivers as intuition, comfort, intrigue, and positive feelings.
4. You can do it anytime of the day from the comfort of your own home. You don't have to worry about anxiety while talking to the girl (if thats a sticking point for you right now), the awkward pauses that can occur when you run out of things to say (b/c of the nature of the interaction), and spending time or money traveling to where ever she is at the moment in order to interact with her. Now, this is by no means a substitue for face-to-face interaction, obviously congruence is not to be overlooked messaging/IM exchanges but congruence itself can be a fluid thing as a person grows or adapts over their lifetime so feel free to experiment (which a facebook/IM relationship will allow you to do more easily).
5. The continuity of your intereaction with her intrinsically express interest (dont be needy or a creepy stalker guys) as well as keep interest peaked in her mind. I've let too many girls lose interest and fall by the wayside by not following up with them out of anxiety or just lazy forgetfullness to know that this is important.
6. Facebook/IM allows you to get a better idea of what sort of girl you're really dealing with. Personally, I take profiles, away messages, personal info, and pictures in these interactions with a grain of salt b/c I've found it much more intriguing and genuine to get to know the person via our interactions but it's great for spotting deal breakers. For me, smoking is a deal breaker; I cant stand it and it really pains me to see a good looking girl throwing her vitality away like that. Given that, I can just move on and persue 'greener pastures' so to speak b/c time is everything so use it to the best of your ability (you're a valuable guy with valuable time). CAUTION: Don't facebook stalk the girl and worry about how long shes taking to get back to you, etc, etc, b/c we all know that's a prescription for oneitis, neediness, and obcession which are never good and subconsciously ruin potentially great relationships everday.
7. Following up a good day 1 or day 2 with a facebooked/IM sexual insinuation, seed, or inside joke reference can supercharge subsequent interactions and serve as a slingshot into bigger and better things.
8. Last but not least, KEEP YOUR PROFILES CLEAN. Girls
will be looking at your profile once they befriend you! Your profile should be DHVing about who you are, your social circle (preselection and leadership in pictures/ funny or caring walls posts), and desirable interests and aspirations...not about you being plastered in every picture and listing 'getting laid' as one of your hobbies. I agree, it's funny to us guys but its not a turn on for girls. Therefore,

closing will give you a chance to let you gain points with her passively and with no effort on your part. Let your reputation speak for itself.
A FINAL IMPORTANT NOTE:
closing will not get you touched, kissed, or laid! Kino is essential in fostering a physical relationship and that simply cannot be done online. The purpose of the

close is to offer a low rejection start to that relationship. In this form, moreso than others, patience is a virtue but the fact that its hugely passive offers great multitasking-MLTR type potential. But remember, attraction is not a choice...
attraction happens in the recesses of the mind and thats where
closing can be very powerful.
This is the 21st century people! We're obligated to use all of the resources at our disposal to tantalize the HB population. This isn't a foolproof system, but then again, what close is? Sure, girls will flake, not respond to your messages, or generally not be into you but such is life; remain unaffected and unfazed. There are plenty of girls out there and hookpoints to be had so try to learn from the past and go get that HB that is meant to be yours.
