Things can only get better

Hmmm. So much for thinking I'd become vaguely computer-literate. I did the 'simple' template upgrade so that I could have the list of labels on the sidebar, and now I seem to have lost the Commentification mechanism, even though I've downloaded and uploaded as instructed. And of course without it nobody can tell me how to put it back. Plop.

ETA: Woot! That just shows the power of Earl Grey! Hurrah!
