In addition, there is an e-mail list at condor-world@cs.wisc.edu. The Condor Team uses this e-mail list to announce new releases of Condor and other major Condor-related news items. Membership into condor-world is automated by MajorDomo software. To subscribe or unsubscribe from the the list, follow the instructions at http://www.cs.wisc.edu/condor/condor-world/condor-world.html. Because many of us receive too much e-mail as it is, you'll be happy to know that the condor-world e-mail listgroup is moderated and only major announcements of wide interest are distributed.
