I am using a licensed version of Invision PowerBoard.
I am considering getting GF, and it is nice you offer a 50% off "sidegrade"... but I have a question:
What's your upgrade licence policy!? IPB is a one time off license for life, or a yearly licence...
Also, what about languages other than English (I see French and German)... any others availabale anytime soon? If I have to do my own (PT) how do I go about it!?
