the only thing left to do is to re-create the site templates, which is aggravating - I'd been working on them a lot lately, and I wasn't too pleased to see them go away... I thought I had older versions of the templates to start from, but I thought I'd stored them in directory a and deleted directory b, which is where they were actually hanging out. :P
Fortunately I remember pretty much everything I did to them. I just need to do it again...
