Apparently, my html code for the Mailing List Page was screwed up, and it was displaying a “you have unsubscribed” message while people were in fact signing up. (The notoriously screwy wysiwyg editor of wordpress stripped out some crucial tags before I disabled it. #$%%#@$%!! Sorry.)

No wonder I was getting multiple subscription requests from puzzled folks. But don’t worry — I got you all signed up! The mailing list page has all been patched. You are welcome to try again if you wish to. :-) And thanks to Ellen for alerting me. :-)
