What special powers do party leaders have?

I don't think there should be any party leaders. But there are party leaders, and they get full authority over the party. What is full authority over the party in 3.2? Invite, kick, and... did we include disband? I don't recall. Disband is the thing that happens automatically when nobody's left in the party.

Yeah, there's no authority to just full-stop disband right now.

And I can't remember the current state of this: did we get the part where any member can invite?

No, only the party leader can invite.

Okay, well, I want that.

Yeah, that's old party system legacy stuff biting us in the butt right now. In the future, everyone can invite.
