Hi there! Thanks. Link to old board, still there for the moment:

I have asked Helena, the support team person who provided the theme we use, if she has copyright and if so, if she would agree to let us use it for a private forum on phpBB3. If she chooses not to so allow, I can get the same background from the game, and the other bits aren't so important (the borders etc.) as the entire html and css are pretty fiddly (from what I remember).
If you'd quote me a price? I know you say donations, but well.... this is really custom work, and that's a bit more than a donation I think.
