As you know (or should), when you hit 5000 friends you can no longer send or recieve requests. I'm there (again). Eventually there will be enough drop-outs or I'll get the quitters cleaned out and I'll have room again. Last time I just let the messages pile up and honored those requests. Frankly that's a lot of work and clutter. For next time you'll need to list your name here. If you send a friend request through a PM it won't count, you need to get in line here. It will largley be first-come, first-serve, however this isn't a democracy it's a (benevolant) dictatorship and I'm the dick. Therfore, I reserve the right to give cutsies whenever I see fit.
Update 15 May 2012: Perhaps I should explain. There's friends who gave up on this place and left, still I don't want to flush 'em. That's why the clean up isn't a one button opperation and takes time to accomplish.
