Well, it’s all well and good saying hook into the bp init action, but it really depends on when you need things loaded. If you don’t require anything specific though, that action is as good as place as any.
The avatar is BuddyPress feature and the wp-admin dashboard is a WordPress feature. There’s surely a way to code this up, but it’s not implemented out of the box.
As Andy said above, the implementation can be improved, but the @reply functionality is not going to be removed from 1.2 just because it’s not perfect yet.
Can someone let me know whether 1.2 will “offically” support WP 2.9? I will probably launch after BP1.2, but before the merge. Right now, I’m having some issues with WP plugins working on WPMU, but would rather that than BP plugins not working on regular WP.
Yes, BP 1.2 will officially support — and requires at least — WPMU 2.9.x and WP 2.9.x.
You can’t; this is a result of the blog IDs being set by an auto-increment primary key integer in the MySQL database. You could do something like export the database, drop the table (wp_sites, or something), create the table again and re-import your data.
However I am not sure of the consequence on WordPress of this being done so not recommended unless you have time to check all the tables and update references where needed.
Gallery component should be implemented using the activity stream component and it’s activitymeta database storage. I believe this is the approach that the 1.3 Gallery component may take.
