Just as an FYI because I realize there are new-to-me people here (which, yay!) --
I can and will play and chat while I'm at work (you can tell because my AIM SN will be "kmegatwork") with caveats: I might leave my desk with no notice, responses may take longer, I try not to play anything too adult, if I say "I'm sort of busy right now", I really am, etc. etc.
Which is a really long convoluted way to say if I don't rep right away or go quiet, I'm not being rude or anything, just working!
