Ok, I like the collapsing boards... that's pretty cool. If there's a new post, does it automatically expand? That would be nice.
No way to see if there are any unread messages without entering a forum... I liked seeing the number of unread posts in the main index.
In "the blues" color scheme, the unread thread is black... really, I'm mildly depressed
, but not all out black! A deep grey perhaps?
