Hi
FYI only. Some of translators including myself have the experience of having the login problems to fedora.zanata.org, and reported to Zanata team. It sometime ago has been explained by Zanata team, if my memory serves correct, that the problem is actually due to fedora openid login thus nothing can be done by Zanata side.
The bug has been filed at Fedora Infrastructure, and Infra team is working on it. Thought some of you may have interest on this bug. https://fedorahosted.org/fedora-infrastructure/ticket/4710
