http://www.html5gamedevs.com is a nice little forum that I just joined.
It has a nice little audience (If that’s what it’s called) and even though it’s not thriving as well as it could, it’s still pretty impressive.
Develteam is a site meant for people who make art, music, and games alike. The site is updated quite a bit with a nice number of members. Stay up to date with that game that’s coming out soon or form a team to work on one.
It’s pretty impressive. To just look or join, go to develteam.com
