To solve this, we have a couple of options:
1. Start using the defaultcc plugin for trac such that emails for the
blocker tracking app are directed to a new qa-devel@ list
I don't expect blocker bugs app to grow into monstrous dimensions (should I?), so I
don't see a problem keeping it in Fedora QA trac. As long as we send the notifications
to qa-devel, it's fine. And we can always adjust in the future.
