They need to make bot events, because like gricey said, events are baised. Or, make it so you don't have to pm staff to join events. They could easily favorite people and summon them without pms or not summon someone else.
1). Make warpers you gotta run to.
2). Make broadcast that you click "join" to join the event, then if you don't click it in time, sucks 2 suck.
