What should be the main tags on the site?
Tagging by game is obvious, any question specific to a game should be tagged.
I don't see the point of board/card tags; they supply very little information and many posts won't have them. Perhaps if a question is not game specific then that would work.
house-rules is a great tag. Could we use
rules-as-written or perhaps just
rules for rule questions that don't invite people to write their own rules?
PS this would be community-wiki if I could. At least I don't get rep for it!
