At a risk of even further derailing this thread (sorry Cloaked!), what on the earth do you need 10 XenForo licenses for? I've never administered a XenForo forum, do they force you to purchase a new license for each forum?
That's quite shocking to me if so actually. I'd have thought buying what is a relatively expensive software package would entitle you to use it at least more than once...
This being said, surely you don't have 10 forums in the pipeline...? Or maybe I'm wrong and you have ambitions to become the busiest webmaster/admin in history.
