I suggest there be a forum for the Galleries since no one knows they are there except for that small text link at the top of the page.
Additionally, I suggest that the forum layout be restructured so that more than the current thread in each category is visible when visiting the web page. That way topics can continuously be contributed to even when new threads are started. I think that mosr people just look to current threads and leave. Also I find that subscribing to a forum doesn't do anything. Some get me an e-mail when there is a post, and other don't.
While I'm making suggestions, I also think that all forums of similar topics be grouped togerher on the page. I think that the 35mm slr forums should be moved up underneath the digital camera forums. A lot of the questions asked relate to both. Then medium format forums followed up by panoramic forums. All camera forums logically grouped one after another.
I think that uniformly, all forums be set to us UBB code as the default to make it easy to post links within posts.
