I've just switched https://l10n.cihar.com/ to Weblate as I think it's stable enough to replace Pootle installation there. This change immediately affects translation of all projects which were done there - phpMyAdmin, Gammu, Wammu, GePeS or Ukolovnik. In addition Weblate itself is also being translated there.
Your old usernames and passwords should be valid (in case you've activated the account and used it in last year), but you might want to adjust your profile as the settings were intentionally not imported (many users had corrupted name in Pootle and hope this will let them fix it).
Let's see how many bugs will this switch reveal, but I expect it will work quite smoothly.
