I asked this:

Auto-forwarding messages on a Facebook group to a mailing list

on WebApps.SX ; on second though, I think maybe it's a better fit on this site (e.g. because it doesn't actually have to do anything with a mailing list and is just as relevant for individual use), but I've never migrated (or cross-posted) anything myself, and I don't want to get shouted at for doing something I'm not supposed to. What should I do?
