At some point everyone comes up against a SAS-related question they would like to ask for help on, or wishes to advertise a SAS-related conference or studentship. Currently there is a SAS mailing list, provided by the IUCr, which is both moderated and archived (with a pre-2002 archive here). SAS practitioners are strongly encouraged to subscribe to this list (and indeed the IUCr do view the number of subscribers and posts as an indication of the health of the SAS community).

The ATSAS developers at EMBL host some forums particularly relevant to biological small angle scattering.

There is also a SA(X)S-related blog site run by Brian Pauw called Looking at Nothing which is worth a visit.
