We have an "Aufenthaltsraum server" on which some useful services are running. It is available on aufenthaltsraum.cf and aufenthaltsraum.tk as well as the IP addresses
There is also a maintenance feed where news about the services are posted.
If you want to use or play around with the server yourself, you can ask Aras for an account.
We use Integrity to automatically compile stuff, most notably theses. If you want one of your projects to be built automatically, you can ask someone who is already using this service to help you configure it.
This wiki is mirrored on our server.
Blackboard for gaming groups.
