Welcome! My name is Sofus Rose, and this is a GitLab server that I host.
Please contact me (https://sofusrose.com/contact) if you need/want an account - for example, if you want to collaborate on something.
I do all my development work here, much of which is open source. Non-trivial open source work is also mirrored to GitHub (https://github.com/so-rose) Incidentally, the webhook server of mine that does so is also free software (https://git.sofusrose.com/so-rose/gitlab-hook).
