Lately we've gotten several application requests which we're happy to review. The thing though is for now, we're not actually putting up any new forums until we've got some things better squared with our resource problem.
In response to that, we're actually starting the migration process of moving our forums onto a phpBB3 platform. phpBB3 has been out for a couple years, but we've been waiting for a few things: elimination of bugs that come with new software and development of phpBB-approved modifications that can supplement the forum with needed improvements.
Nowadays, most of the critical bugs have been cleared since it's been out for some time and deployed on many large-scale projects. And several important modifications have been released (such as a good points/cash system), so now we're ready to start moving forums over.
