I have just finished migrating the services mentioned above to new domains, and also to hosting on the lemmy.ml server, instead of my personal server. This makes sense because all of them are used almost exclusively for Lemmy development. It will also allow @dessalines@lemmy.ml to administrate the services in case of problems.
The new domains are:
Gitea: git.join-lemmy.org
Weblate: weblate.join-lemmy.org
Drone: drone.join-lemmy.org
There are redirects in place, so you will automatically be forwarded from old domains to new ones.
Gitea is an alternative to GitHub that can be self-hosted. git.lemmy.ml is an instance of Gitea and will exist alongside GitHub as a mirror to the GitHub repository.
For helping with translations you will have to go to weblate.lemmy.ml
I don’t see any option for SSO so you will have to create an account there.
