Fedora translation projects were migrated to Transifex.net on Friday, February 18, 2011. Projects on Fedora Hosted will be given a chance to opt-out, and those who don't opt-out will be migrated over the next two weeks.
Why now and not wait for the next version?
We are lacking resources to manage our current infrastructure, and the L10n group decided that the Fedora 15 translations are in danger. All related Fedora groups (L10n, Infrastructure, Packaging, Docs and Board) have concluded that there is little risk in the move.
Where do I get the "tx" command-line utility?
The transifex client currently available in Rawhide (pre-F16), and in the "updates-testing" repositories for Fedora 13, 14, and 15, and EPEL 5 and 6.
Where can I get more help on using the Transifex client?
Additional help for the Transifex client is available at transifex.net
