There was a time when I thought my quit group was intentionally bumping me kinda of a passive agressive way of saying "get the hell out", but it was only Nic whispering lies in my ear. Keep posting and don't be afraid to give a little feedback to guys who always seem to bump people without checking. If you post and bump someone, go back and fix it and note it. ex: gwb - 310 (bump fix). It lets people know you are doing your part.
You can't always go back 10 times a day to check. If you get bumped, then contact the sheet guy to fix it if you want. Whatever works for your quit.
