A migration to another open source infrastructure is planned. This will include web hosting for http://www.nmr-relax.com, source code repositories, bug and other trackers, new reports, download pages, and possible a svn to git conversion.
The NESSY relaxation dispersion software is supported in relax. NESSY input project files can be created through a single relax user function, after all base data has been loaded. Note that NESSY is in maintenance mode - the project is currently dormant with no active developers.
