I tried out what turned out to be a crappy new format widget for this blog. It ate a faithful commenter's comment and asked me to Approve it, but didn't tell me HOW.
In my zeal for retribution I have tried to restore the original backed-up template, and it seems to have worked, but the last 4 posts' comments are gone. Annoying.
I still have them so I'll either just post them as edited extensions to the post itself or as standalone posts. Sorry for the inconvenience. 1st things 1st - I have to make sure that comments will be enabled from this time forward.
Edit: OK, at least it looks like they will work going forward. Beware Disqus.
