Did you see the information about the site upgrade?

I usually just land on this page, but went to Forum home today by mistake. This site is being upgraded on 1/16. I hope it goes better than the ADA one did! Check it out!

I'd say the last upgrade worked seamlessly, except for the "seams" caused by the "groups" which they just fixed? I didn't have any login problems at all.

The ADA site did "one" upgrade? What were the others called?
