Heyo...

To add me to your friends list, I need to recognize your name. If I have not gamed with you in the last hour, do not share a mutual friend with you, or know you from prior contact, I will almost certainly ignore your "blind invitation." In fact, I will probably still do so. If your name isn't immediately recognizable by me then I will check my wall to see if there is a message of explanation as to who you are. If you forget to leave such a message and your friend invite is therefore dismissed, do not be surprised. Just post on my wall and try again. I'm not unfriendly, I just don't have time for unsolicited invites.
