Translation Status Pages
To update branch information for modules, there is an interface on http://l10n.gnome.org/module/<module-name>/edit/branches, which should be self-explanatory. Of course, this interface requires a login (ask claude at 2xlibre dot net if you need one). When you're logged in, an edit icon appears right after the branch names on the module page.
Other modifications (teams, people, etc.) require the use of the complete admin interface, which is currently only open for a restricted set of users.
But please respect the defined procedures in TranslationProject/CoordinationActions unless your changes will be reverted.
