Thanks Dave, have updated :-)
I've started pulling in data from another site, so its starting to look better as a whole
The forum page is looking a little ragged, and really would look better on a full page without widgets ... but hey, I'm not complaining.
I am experimenting with the following plugins at present, and all seem to be working:
BP Group Documents
Buddypress Rate Forum Posts
oembed for Buddypress
I'm not using BP-Links as it doesn't appear to like the Lexikon plugin, and the latter is more important to me, at least at the moment.
BTW: Anyone have an idea how I can turn off the drop down function in the page navigation?
