Hi folks,
We've had some trouble with the existing "welcome to Fedora" repository, unfortunately. We're trying to recover it, but in the meantime, we've set up a new one here:
https://pagure.io/fedora-join/WelcomeToFedora
If you had your welcome to Fedora tickets in the older one that are currently accessible, please drop us a message and we'll open new ones for you on the new repository. We can merge them back in once the original repo is back up.
Sorry for the trouble.
