BuddyPress.org

@jtle918,

1. White screens should show up in your server logs; check the offending process and adjust to taste.

2. Facebook Connect Plugin will probably need some adjusting for BuddyPress1.1. I know other people have experienced some lag, memory, and slowness issues using it.

3. Yay integration!

4. I know Burt hasn’t updated the group blogs plugin in a while, but your best bet to set default themes and settings would be to check out the WPMU new blog defaults plugin. You should be able to adapt that to set the blog theme on creation.
