I didn't buy the license of him. But if you guys any day would say "DAMN I AM SO TIRED ON THIS UBB THREADS LICENSE! Lets give it to someone" then you know I am happy to take it.
Also I would of course offer free ads and links etc. If I am honest, I won't pay anymore for any forum software maybe except in very rare business events or something.
I love the look of UBB Threads 6 and UBB Threads 7 but I won't buy it (I guess, it is just too expensive, for a very long while).
