At any rate, I assumed the worst that had happened was that I'd need to add the new blogs again. I waited to do so until I reached the library last night, then became too engrossed in The Last Witchfinder to bother with blogging until I was back home again and wanted to add the Morrow to my list of completed books in the sidebar.
What I discovered is that not only had all the content I'd ever added to the template vanished, but much of what Blogger had put there was gone as well.
This morning I copied and pasted template material from my other blog and have made a start at restoring links. I didn't have haloscan for comments there, so it appears I've lost everyone's recent comments here. Considering that haloscan placed ads in them and didn't archive, I'm not likely to attempt switching back.
I've been toying with switching the template altogether for awhile; don't be surprised if things look very different here the next time you return.
And please note that I managed to write this entire post without cursing once.
