Sorry for putting this in Trac - it probably belongs on the forums, but of course you can't register for the forums. I sent a manual "please register me" e-mail to The Tick a week or so ago as instructed, and never heard back.
Anyway: Trac sends a confirmation e-mail when you create a ticket, but it doesn't seem to send any followup e-mails. (I run my own mail server and can see that it's not getting spam-blocked or anything.)
I've seen Tracs that send no notifications, and I've seen Tracs that send them all, but I've never seen one that does this; I'm assuming it's a bug, but even if it's intentional, it's confusing - when I see the initial notification, I assume I'm going to get update e-mails as well, so I don't bookmark the ticket and check back.
I'll try adding myself to the CC field this time, but if that's the case, maybe add some helpful text to the new-ticket confirmation?
