The aims of the WET are: (1) A collaboration of people interested in asteroseismology and time-series measurements to discover the internal details of their observed objects. These objects are traditionally chosen from the classes of variable white dwarfs, but can and do include other interesting objects, like interacting binaries, Ap stars, and the newly-discovered sdBV pulsators. (2) World-wide, multi-site, simultaneous observations of astronomical objects with similar instrumentation and observing techniques. (3) A central interactive headquarters operating during each coordinated multi-site observation used as a control center for run planning, operations, and often, analysis.
