 +<bootnote critical>This article is mostly deprecated, as the Jabber-Server is currently not maintained and most communication switched to the university's [[https://www.uni-bielefeld.de/einrichtungen/bits/services/kommunikation/teamchat/|Matrix server]] where you can also find us in the space named [[https://matrix.to/#/#fs-technik-space:uni-bielefeld.de|#fs-technik-space:uni-bielefeld.de]]</bootnote>
  
 [[https://en.wikipedia.org/wiki/XMPP|Jabber/XMPP]] is a distributed instant messaging network and the Fachschaft is running a server for the Technical Faculty. It can be used by all students and employees, basically everyone with a TechFak-account. As it's not operated by a company with commercial interests, you don't have to worry about anyone profiling you or selling your data (unless you use a commercial client). [[https://en.wikipedia.org/wiki/XMPP|Jabber/XMPP]] is a distributed instant messaging network and the Fachschaft is running a server for the Technical Faculty.
