This question may demonstrate my lack of understanding as to how Buddypress and Wordpress integrate.
My developer setup a multisite installation for me and I setup a number of blogs and have been experimenting with various plugins. He also setup a second installation on which I installed Blogs MU. I have been playing with it and it works fine for what I want. My aim is for the Buddypress (Blogs Mu) theme to be the social end of the multisite. Each blog on the multisite is to be a self-contained community news site but with the ability for members to share resources etc across the broader community. My developer has given me the impression that achieving this outcome requires a lot of work, this is his first work with Wordpress.
I then came across this post which suggests that it should be easy to achieve.
So I installed BP and network activated it, and then installed Blogs Mu on the root blog. The outcome was that some items ie groups, forums, activity and members appeared on the menu bar but as pages but without the ability to create groups etc. The theme specific Buddypress settings sub menu didn’t appear in the theme options and there are no settings or other options under Buddypress on the Network dashboard side menu.
Any guidance gratefully received.
