everyone's playing dota 2!

If you don't want to bother yourself, give me officer rights and I will sometimes do it. Or allow all members to create these events. But this is a risk because members can spam

I would suggest officers to schedule gameplay event sometimes (but not too often). Once per week would be good. To make it easier for players to gather and play this game together
