Given this announcment today: http://magic.wizards.com/en/articles/archive/news/wizards-coast-community-forums-be-shut-down-2015-09-16 I just wanted to pop in and invite anyone who is interested to come visit the Forums over at The Mad Adventurers Society.
We're always happy to see new people and we offer a friendly environment for your gaming discussions as well as many fine articles and podcasts about tabletop gaming and RPGs.
See you there.
I am pretty sad to see this announcement. I have not visited much lately as the constant changes were a bit confusing to me, but at 3000+ post I did have my share of fun here.
Another place worth checking out if you like talking about D&D and RPGs on forums is The Piazza: http://www.thepiazza.org.uk/bb/index.php
Our community has been around since 2008 and fans of all editions are welcome.
