Very slowly.
I finally got around to importing the userids from the old system tonight (last night?), but the old passwords will not work, as the storage methods are different. It would be interesting if I had spent time trying to crack them and then install them, but it’s not worth the effort.
You can get a password if you had a prior ID by clicking on the forgot password link. The system will send you an email with a link and you have to click the link, at which time it will send you a password.
I may even get some of the old content installed this weekend. Who knows. Miracles do happen, so they say.
