There is an Overleaf server running at tex.let.rug.nl.
To use the Overleaf server, send a request for an account to Peter Kleiweg. This is for staff of the Faculty of Arts only. In some cases, students can get access too.
Interested students should include in their request their study program and the course for which they need access as well as the name of their supervisor in the case of a thesis project.
