Thanks for the comments Charles - so far nothing I have read is turning me off. Dalantech hit some big 'needs', ones I pretty much agree with, so its good to see a number of them in the implementation.
I cannot see Users losing the ability to choose posts/page, sortable columns on postlist, and daysprune to be a big deal - the vast majority of my users don't access those functions.
Has there been any external studies done with some UBB.Threads admins on what is used and what is not?
