The problem with slow migrations to somewhere new is that the old one still get used. There needs to be a clear cut off date for the killing of the old forum otherwise it'll never die. Lock it down, make people move.
Agreed. Leave the old one where it is for now with a message saying where we can now be found, and then kill it dead. If we can import over the old stuff then that'd be great, but otherwise let's have (another ) clean start.
