For LC itself I agree within the same criteria I stated in sdave original suggestion on same subject linked here Open Discussion Suggestion
I think this would be nice for each game if wish to talk within personal game's community.
We already have this for overall Aeria known as Odds and Ends. However as I stated before many like to also communicate within own game and among their own community.
Also in same thread as I stated re my original suggestion for farewell posts this would be the right place to put them, rather than current trend of moving to general aeria games as this causes ill feeling to some.
So I agree for all games to have their separate forum for odds and ends or whatever they choose to call it.
