Hi koan, long time no see, glad to see you again.
Yes, unfortunately the registration emails are not being sent since a while. These days I'm doing a (long overdue) forum upgrade, I first want to check that this issue is not related to the forum software being too old for the PHP version used by our hosting service (ibiblio). In case this won't fix it I'll open a ticket to the host. In the meantime I usually manually accept all the registration requests, these days unfortunately I was quite busy, sorry for the inconvenience.
