I'm a little late to the ballgame in realizing the forums are being shutdown. What are the best alternatives and places to go? If there is another thread on this already, I'd love a pointer. Many thanks!
ENWorld.org seems to be where a lot of people are moving to. They have a pretty extensive forum, and a lot of the class guides that were posted here have been moved over there or are in the process of being moved. I signed up over there shortly after I got the news. It seems like a pretty friendly place so far. Just make sure and read through the forum rules, different message boards have different codes of conduct, and we all want to be good neighbors in our new community 
I recommend Enworld. It's a great site.
