When developing this, I made a rather foolish assumption. I assumed that the implementation of phpBB in Dragonfly (which is what I use) would be pretty similar to the full version of phpBB. I always intended to test it but wanted to get a release out that I knew worked, at least with my implementation.

It seems that the database structures may be rather more different than I thought. In particular, from a quick look at the sql script used to create the tables for phpBB3, the way that groups are handled seems completely different.

So, for the moment, the addon only works for the built-in Dragonfly forum. I will get a phpBB3 installation up and running and hopefully update this addon with options to make it work with it.

Apologies if I got anyone's hopes up. Best case scenario is that groups are handled in essentially the same way and it's just some minor sql changes to make this work, but I think it's going to be a bit more work than that.
