I still don't see anything like this, but I think it'd be a really good idea. The SB isn't very reliable to keep track of new blog comments, and the displayed blogs on the main index only show the newest posted blogs, not the ones with the newest replies.
So what are we going to do with Blog posts? Besides having some appear in the featured thread/blog area? Could we maybe set up a Recent Blog area over on the side below Latest posts?
The text above different areas, like Members online, recent posts, etc... can barely be seen on the Dungeon v.22 theme. I'm using it over the others because it more closely resembles the look of the previous version of it.
