with the old forum, I could quickly go to subforums and view topic specific posts quickly and efficiently. if I wanted to see threads on Parts and modeling, head to that sub forum. If I wanted to see threads on sheet metal, head to that subforum. if I wanted to see threads on Visualize, head to that subforum.
Now, I have to skim all the posts on hundreds of subjects I could care less about just to find one on a topic I do care about. total time waster. It's akin to having to read an entire newspaper front to back looking for one article when the newspaper isn't organized by sections.
