I'm not sure if the Help Wanted / offered section is the best place for these sort of things but I'm curious about I have this idea and I need some feedback or I have this game but I'm concerned about this issue. Something where creators could ask for feedback or get discussion about their idea. The help-wanted seems a little bit more official but maybe that's what it's for anyway and I'm just missing the point. Am I?
Depending on what you're asking about, I'd say Theory (for more generalized and broad topics) or one of the subcategories for a specific system under Design would be the perfect place for you. Help Wanted is more intended for looking for, say, a layout artist, writer, or sensitivity consultant. Hope that helps!
