Well correct me if I'm wrong, but IMO TechIMO is for everyone. I used to frequently visit the forum at guitar.com before. Then someone started posting really disgustong pictures there. I just left. I was really offended. The moderators weren't doing their jobs...
So you've got to be careful and be sure to warn if you're going to post anything that could offend anyone. Kinda hard tho...but IMO we should try to keep TechIMO's good reputation up as high as possible.
Just my 2 cents. I wasn't offended by the pic, but I think Fingers did the right thing by removing it.
