Places to Discuss Game Publishing and Design
There are three big ones.
- BGDF is the best place to discuss card and board game design. It is read by a number of people in that industry, but has fewer active professionals from the RPG and hobby game industry.
- RPG.NET has many forums of interest. Questions about industry stuff go to the Business and Publishing Forum, then there's the Art of Game Design, a section for hiring Freelancers, a place for Ads and Open Promotions, a Playtest Registry, etc. Poke around.
- The Forge has forums on game design, publishing, and on conventions.
