I'm wanting to convert one of my forums to Xenforo from VB, but don't want to put my userbase through multiple updates in the same year... And, I want to be running on 2.0 for sure. Will I have to do a complete style redesign when upgrading from Xenforo 1.5 to 2? If so, I'll wait for the 2.0 release... but would prefer to get started now.
