The ET commands would be this:
/gwarsevent1start
-This would start the event, And Gwars would reset the timer, And enable the Auto-Look/Class When warped.
/gwarsevent1stop
-This would stop the event.
I know, Its probably not that simple. So, Just forget about commands, unless this will actually become an Event, Which I doubt.
Sincerely,
Desear
