Thanks for the kind words ladies.
I know it is frustrating not to be able to utilize the full features of the forum. Trust me, if I knew how slow the forum will end up after the upgrade in August I would have never done it. Since then we had 145,000 posts so I did not want to lose all that content and roll back. We had to do it the hard way by slowly downgrading everything.
There are some issues still as you are all aware. You can only reply using the quick reply box and the old threads give out a 500 error. Some other areas (like blogs etc) do the same thing. Hopefully we can get everything sorted out tonight.
