The University of Twente has set up "mailing lists" for employees and students. These are e-mail discussion lists to which you can subscribe. All subscribers can join in the discussions by sending an e-mail to the list. This e-mail is then sent to all subscribers. LISA manages these mailing lists using the List Server.
The UT's List Server provides a list of all existing mailing lists. An archive is also maintained for many mailing lists. For some lists, this archive is public, however for other mailing lists it is only available to subscribers. These archives can also be found on the List Server.
