Pete...

I'll be happy to help you out with this... I can guarantee you the earliest I could get to it would be either Saturday or Sunday. It might take me a few days though, given the level of work I have right now. Hopefully your not in a huge rush.

I cant remember but did you say there was modifications to the core files? Will it just be a standard upgrade plus getting this plugin to work?

I'll send you a PM with my contact details
