After reading for weeks about xenforo I decided to make the move because my forum software is obsolete, right now I'm doing a test install for my smallest forum (foroshonda.com) and later I'm planning on moving my biggest forum (ek9.org).
As I'm typing this I'm doing a test install. And I'm very impressed with the importing interface I only had 2 issues with usernames that included a , not big deal
Unfortunately I will lose my user albums, but its not a big deal for foroshonda.com, but I'll need to find a solution for ek9.org in a near future.
I hope I don't struggle with nginx rewrites hehehe wish me luck.
