Re:Why not integrate phpBB?
I think the discussion of enhancing Tiki forums vs using a 3rd party package is always ongoing. Personally I am in favour of the first because there are only so many 3rd party features you can integrate without taking the risk of breaking the application where integration is concerned. However, if you plan to write a connector phpBB->Tiki then I think this would be very much welcomed by both communities. So good luck with that! Some things to consider I think are:
- user authentication
- private messaging
- search/indexing
