Not anything to do with the styles, but what happened to the "Recent Posts" box??
I'm still partial to coffee!
The 'Recent Posts' box wasn't updating properly, sometimes it might take all night, so it's on the shelf for now until we can figure out the problem.
The 'Active Topics' link above in the Navigation Bar will give the same information and more. (by Recent Topics or Posts)
If 'Coffee' doesn't end up the Default you can still set your preference for that style in 'My Stuff', making it your own Default.
