I have been using 4x for well over 2 years now (closer to 3)...and actually I really like it. And my members like it a lot. Just last week one member was talking to me..asking about what software I was using and how they loved it. (they are used to 3x) Of course some of my modifications have improved my forum...and I have had people in the past to help some out with any problems..but so far, not even close to a hack. (knock on wood).
