We transferred this GitLab instance to git.bau-ha.us. References to gitlab.bau-ha.us should still work. But it is good practice to migrate your projects to the new domain. If you experience any problems feel free to contact support@m18.uni-weimar.de

Merge requests are a place to propose changes you've made to a project and discuss those changes with others

Interested parties can even contribute by pushing commits if they want to.
