I'm going to bite the bullet and adapt it to our (slightly unsuspecting) community. And give it some real world testing from their "end user" point of view, as opposed to our administrative point of view (I find non tech people turn up things we tech people miss).
But its also going to give me a small feel on how well add-ons and current styles work with XenForo 1.2. I've decided that when I first install it, I'll have everything disabled and from there, slowly enable things and see how it goes.
So who here other than myself is going to be bold, not slap this onto a test site first, and just run the upgrade & enjoy the ride?
