First, I have been provided access by Ed to those things that allow me make changes and explore methods to gather old posts and save them. Thanks Ed!
In addition, since we were getting clobbered with pesky spam members, I have created a step to require approval for any new member wishing to join. They will be able to set up a registration as normal, but an email will come to me prior to allowing them in. I can either approve their registration or forbid it.
All existing members should experience no difference to getting in, other than possibly having to log-in appropriately.
If anyone has an issue, please let me know immediately.
