It is my opinion that all 'the powers that be' are doing an excellent job of the migration! Are there bugs, sure! Does the forum look 'different', sure! Have things changed, sure! I believe it's human nature to resist change of any kind, more than not. In the end, the old quote from W.C.Fields stands true.... "You can please some of the people all the time, and all of the people some of the time.... but you certainly cannot please all the people all the time!"Believe it or not, I can't even edit my own signature. We will look into fixing this soon!
The move to vB to XenForo was a huge undertaking. Permissions had to be re-done, threads migrated to a whole new format, and in fact the entire structure of the forum categories needed to be changed. Now that is is live we are fixing the "big things" like missing/outdated threads, and working our way through the bug list.
A month from now, all the grumbling will be a thing of the past, and I really do believe a LOT of folks will be having nothing but praise for the new forum format, and all the changes.
Just my .02 .
