Nangband is a new Angband variant which is currently in its first "development cycle"; ie. it has not been released yet. It will feature lots of things by its first release, but as few of them have been written yet, they can't be advertised as such.
Berlios.de hosts the project, including CVS, bug reporting facilities, website hosting, file releases and mailing lists. Many thanks to them for hosting it, even when certain other organizations (mentioning no names) rejected us.
There are two mailing lists for Nangband; click on one to be taken to its subscription/unsubscription page.
