Re: Questions about groups.
1.) adding someone as a moderator is the same as admin pretty much
3.) BP is not currently setup to do this, one way to accomplish this though, instead of doing <?PHP if is admin?> to create groups, do <?PHP if user is level X ?> then you can manually select users and make them authors or contributors… then they would have the power to create groups. this would also give them power to create blog posts on the main blog, so you may not want them to have that power.
hopefully in the future, BP will have more control over giving users authority levels and what not…
4.) bp is not setup to do this either yet. you would need to modify the core to allow that content to be displayed to non-members
everything you want IS possible, but would require some modifications to the core of buddypress. and this is not suggested
