I know they are in beta but the following question begs to be migrated to [linguistics.se].
I wonder if our passing relevant questions to other SEs would help them get out of Beta as well.
Normally migration paths are not set up until after the target site is out of Beta. I think the idea is to avoid swamping smaller sites and to give them space to determine their scope.
I don't think Linguistics SE will graduate anytime soon, though, so it's a bit of an odd situation.
