Today we are pleased to announce the D-PHYS eGroupware collaborative calendar solution http://groupware.phys.ethz.ch. We have put a lot of effort into the task of finding a groupware package that works with as many different clients as possible and offers the widest range of features. So if a synchronized calendar service could be interesting for you, give it a shot. Please also consult our readme detailing the different sync solutions.
If you’re still using our much older https://webcal.phys.ethz.ch/, please move on to eGroupware as soon as possible. This service will eventually be discontinued.
