"..But don't know enough about business to think ahead."

That much is obvious. Look at the way this was brought about. Tim makes a statement disguised as a discussion and then insults people as he bans them from the one forum that keeps them informed about their products. If he worked for me I'd have fired him over a decision as destructive as this. But then although my family depends on our business we don't see our competitors in the same light as Tim seems to see other sites. Quite the opposite. We're friends with them and help each other out when it's needed. Apparently that type of thinking is beyond Tim and others here. To me, Renderosity was always the central point to the 3d art community. "Was".

That ANYONE thinks its right to accept money for someone's product while they are banned from the forum where discussions affect that product is beyond me. It's not logical at all.
You don't implement something like this in the way Tim did. If someone is selling here they have a right to be informed of policy regarding their product. If Renderosity needed to create an even more private forum that was restricted to their idea of "competitors" that would have gone over much better than 'leave your product but don't let the forum door hit you in the arse on the way out'.
