Yeah, I can always just make an email chain to inform people of new compos, that’s no real problem. Sorry you missed the last one. 
would be better to be able to be notified of “new topics” in a board no ? so people interrested may ask to be notified of new topics in " JGO Comp -Petite" board, could alos be used for other boards
EDIT: oups seems that already possible :), so no need of mail list
