All notes from the non general section appear to have gone away.
I think I just figured it out: If you're not logged in (e.g. other PC or just closing your browser) you need to login first to see all messages. If you're not, you only see the first thread (mine, hehe) in the general forum. Strange. Also noticed that I started this thread as 'unregistered'. Didn't know that one can post without having registered. Guess a few more 'features' to be worked out.
Everything mentioned in this thread is as designed. Non registered or not logged in users should only see the General, Tech, and Bug forums. Basically, motivation for people to register in order to see everything. Anyone can post to the Bug forums for now as there may be registering questions.
