I really waiting the decision about the xenforo case in January.
i test the forum from about 3 months and discovered many options and install a demo copy on the localhost for try it and i'm very interested with it and want to be a liscensed member.
I used VB for about 4 years, it is good
but i liked xenforo more, this is my personal view
anyway i just wanted to say i strongly hope xenforo win the case and can update and develop this nice script.
