It works on anything where there's a group. If you are in a group, and you type /grss whatever, it will take a snapshot called "whatever." It's independent of location. The only exception is auto-snapshotting only works on pre-defined locations.
Belated thanks, Chops. We're happily using GRSS for all of our party and raid events. However, I have a question born more of curiosity than practicability: Suppose I predefine a destination. How does GRSS know to take a snapshot automatically? Does GRSS compare the name of the boss killed with its list of pre-defined destinations? And does GRSS support custom destinations, i.e., destinations added by users?
Cheers,
