There are a lot of topics annoucing people leaving. If you find it annoying my recomendation is don't look in there. We stuck all of these topics into a sub-forum for a reason, so it doesn't mix in with the stuff people want to read. (Not that comings and goings are important or not important). People leave, people come back.
As for people 'bitching' in topics, or whatever pedlya said, thats what this area is for, its called Forum Feedback. As I said to the people who hate leaving topics, don't read this area, if it bugs you that much.
In general, we're working on reducing the amount of flaming on the board, right now the only problem i see with the leaving topic is, people flame eachother, and are very rude to eachother. If it continues and our moderation staff has issues controling the area, maybe we'll shut it down. I doubt that will be the issue, I have faith in Hal, and his team. We're trying very hard to get on top of issues that were left for us to deal with. Alex did a great job cleaning things up, but there are still some places that need mopped up, and Alex and I knew that when Alex left.
So please give is time to control these issues, and please keep posting about issues as you see them. We want to hear these things, and we want to fix the concerns users have with our community.
