Google Groups import

That’s a good point re: e-mail addresses. I suppose at some point in the future once most of the membership is transitioned, it might be possible to have posts linked to members where they used the same account, and where that isn’t the case have the post linked to some sort of dummy account with some sort of tagged indicator of who posted in the post itself. That sounds like it’s getting quite complicated, though, and maintaining some sort of archive is probably far more straight forward and accomplishes the same things.
