It's not over yet. I've downloaded the database of the board settings, and our custom design, but I can't make a copy of the board itself, all our posts, until I can get into the cPanel. With what we have, we could set up a board just like the one we have . . . but with no posts.
I'm hoping that I'll hear from Voronwë this evening, if not before. I'll be watching for an email and will start the backup just as soon as I can. Or he may start one first.
I'd be willing to commit to doing a backup regularly, once a month or more often. It doesn't take much time to initiate one. I've got very fast Internet, and my computer automatically backs up both to an external drive and to the cloud.
