Back Up!
Somehow my entire site was wiped up and I lost everything... well, almost everything, because thankfully I've been storing my files elsewhere. After a few days' worth of work copying the content of the website from the original (thanks to Wayback Machine!), the site is for the most part up and running again. I'm not done yet, and still need to make some more adjustments. The fact that my previous website is wiped out is unnerving... possibly a hint to change hosting service?
