To add a group for a hosted project, use the New Group link in the account system.
Group Name should be the project's name, prepended with the SCM being used, e.g.
Group Owner should be the project owner.
Group Type should be the SCM being used, e.g. bzr, git, hg, or svn. (This is what we filter by for allowing access to fedorahosted.org.)
Other fields may use the default values.
The new group data should sync to fedorahosted.org within a few minutes. If you want to force a refresh on hosted1 or hosted2, run:
sudo fasClient -i --force-refresh
