@Boone Gorges, well I do have the same problem in BuddyPress 1.2.3 . I can find the rule in /bp-blogs/bp-blogs-classes, but……
the file bp-activity (in the root of BuddyPress) changed so much, that i don’t know where to find the rules like you’ve discribed.
Will you help me again? Or maybe you know if there is a plugin for it?
With regards Anja (afoka)
