I actually had a previous WordPress blog at this domain (though with a different hosting provider) before I discovered the hard way that I didn’t actually know how to restore the database for a WordPress blog from backup (which is extra-embarrassing for a librarian, of course).
One silver lining is there weren’t many posts there to be lost in the first place; another is that it made for a decent occasion to switch domain registrar and hosting provider.
All my best stuff is in the future, anyway.
