The "WGE" means Women's Global Event. Both of the events are taking part in this effort by the PDGA to get more women participating in disc golf. You can find more information at http://www.pdga.com/women/global-event
The events are still run the same however there is simply additional incentive to encourage women to participate in PDGA events. :)
DO IT! Do it soon though. I'd like to see her get a WGE player's pack (on top of the one we give out) and there's only about 100 left - maybe less.
