BuddyPress.org

re – BuddyPress Community theme – Did you even activate the theme or read instructions at premium.wpmudev.org/project/buddypress-community-theme/installation/ ? Also, the theme is a premium theme and you should have free theme support there.

“BuddyPress Default 1.1.3 by BuddyPress.org which seems to have the Community theme embedded in it”

– uh, no Community theme embedded at all – or do you mean you activated the theme?

Re: your confusion re themes – only bp-default child theme and bp-sn-parent are packaged in BP 1.1.3 BP plugin
