It was so long ago (July lol) I'd have to look into how it works again, I just remember it being a royal pain in the arse. If I remember correctly there was in integration script but it wasn't up-to-date. Gizzy and I had many problems, but it somehow eventually came together for Threads 7.1 (which I'm still using).
When 7.3 is released I'll have to look it over again to make sure it still works, and will try and post something on ubbDev. But in the mean time, you can read over the initial thread
at Dev, and also the original threads at Tufat here
It's worth noting that I wasn't able to get the developmental version (4.8) to work, so download 4.7 if you want to try it out.
