BuddyPress.org

Thanks for the replies everyone.

Xevo – The vague idea was for very many fewer sites and blogs than that, but your point is taken.

Andrea – No, it is on a VPS. It was actually following some of your posts on other sites which made me have a look at Multi-Site Manager.

DJPaul – Thanks for the link. Had not seen that and it has sparked off another idea. So, you can have BuddyPress sites within BuddyPress sites, eh?

Is that OK to do?

If I spent as much time actually writing blogs as playing with ideas, the database might actually be in danger of filling up.

Thanks again everyone.
