Please take a little time to read the proventester wiki page at:
http://fedoraproject.org/wiki/Proven_tester

Then confirm that you have read this, and that you will follow those guidelines, and also confirm that you know how to add karma using the bodhi web interface and fedora-easy-karma and then I will be able to sponsor you. (you will also need to apply to the proventester group by logging in to the Fedora Account System.

Thank you for your interest in helping the Fedora Project QA team. I'm afraid Proven Testers is currently closed to applicants as explained at the top of ​the [https://fedoraproject.org/wiki/Proven_tester Proven Tester] page. The group has no function as things stand, so it is "in hibernation". We may resurrect it when Bodhi 2.0 is released.
