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 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.
