I don't know if this is relevant, but there have been a few 'Introduction' posts that have been deleted, as being akin to 'Spam'. If you'd already joined in to those topics, maybe you're getting an alert for a topic that's been deleted..? That's my best guess, anyway, and, if the topic has, indeed, been deleted, you'll get no further alerts from them. Maybe someone Admin could confirm or deny this..?

...and to reduce search time, here's the culprit, in the 'Categories' list on the left...
Anyone care to correct it, please..?
