VSS is not the only variable star organisation (although the only one focusing on the southern hemisphere!). The following organisations mayt be of use to you as you explore various aspects of variable stars.
The AAVSO is an international non-profit organization of variable star observers whose mission is to enable anyone, anywhere, to participate in scientific discovery through variable star astronomy.
The BAA-VSS was formed in 1890, the year the BAA was founded, with the aim of collecting and analysing observations of variable stars. The Section is run by a small group of Officers who deal with various aspects separately but meet at intervals to discuss and decide future plans and policy. Feedback to members is through the VSS Circulars published four times a year and through the BAA Journal.
The Center for Basement Astrophysics (CBA) was founded by David Skillman in the 1970s as a sort of counter-culture version of the perhaps better-known institute in Cambridge, Massachusetts. The single product of the CBA was, and still is, light curves of variable stars.
