Well, I think it's messy looking and the background images are an eye sore, but I just adblocked them and that made the forum look about 7000000% better.
Please add pages instead of infini-scrolling, it reminds me of that reddit site that I visited once or twice. All that scrolling, I hate it so much. Pages keep me organized and make following posts very easy.
Will the mention of the last posts user name come back? That was another great thing about the vb forums, and it's how I knew there were new posts in many threads.
Is there a way to turn off the auto-tracking besides manually doing it for every post? I don't want notifications about replies, I've got my own methods for knowing when I was replied to.
