I tend to use the "Recent Post" section of the site more then I do going through board by board.
It would be awesome if at the top of the forum if I could click on "Author" and it would sort all the Authors out or if I could click on "Replies" and see what topics have new unread replies. Of course that one might be kind of weird because you do you sort it by MOST replies, or NEW replies, or what...
just a suggestion
There used to be an 'unread
There used to be an 'unread threads' sort on the old forum. I don't miss it particularly cos I never look past the first page on 'recent' anyway. As for sorting on author, you can always find whichever author you're looking for, click on their profile and then 'Track'.
