I know this has already been discussed, but check out that Spider-Man discussion forum. Try to follow the linear progression of the conversation, checking the post times. Then just follow the straight line down the page. It’s impossible to follow unless you’ve been consistently posting in that thread for days.
While we’re on the subject (and this is in no way an immediate request for overhaul, just something to look at down the line): I personally don’t feel we need all these sub-page categories for the forum. Their purpose could easily be done with tags; at the very least, we shouldn’t have as many sub-pages. It’s just harder to navigate. Personally, I think we should follow the more traditional message board format and have the most recently updated conversation put to the top of a page.
That being said, I do love the sidebars
