We have talked about other types of additional interest forums in the past, but do to the level of moderation on this forum, we have always tried to curtail the amount of areas required to moderate.
With that said, i really don't think we would be wanting to add another section for an outside interest. When you add one, then it It leads to others wanting a section for knitting, animal husbandry, etc. LOL
So, I would say start a topic in the off-topic section to discuss these types of things.
