Instant Messaging (Chat)

Real-time communication is possible via the University Computer Center’s own instant messaging service (chat server). Similar to ICQ, Facebook or Skype you can chat privately with a person or within a group. The chat is limited to text messages, the data remains on the chat server within the Philipps-University. However, the chat communication is not limited to the university network, so you can use it from anywhere.
