We talked a bit about this today. We think its best to keep the number of different categories to a minimum at least until the activity on the forum starts to pick up.
We’re basing this decision on other forums and chat rooms we’ve seen that have a lot of different categories/rooms many of them go unused and people get angry and frustrated if they don’t get a reply in a timely fashion.
Especially as Odin is so interdisciplinary. Someone who’s sufficiently along in the curriculum should be able to help in any area.
