The party leader can remove members (the leader sees extra icons in the list of party members). There is no way to put members on stand-by.

If the leader is inactive, one member (the new leader) should make note of everyone's Unique User IDs (UUIDs), then everyone should leave the party, and the new leader should invite them to a new party. The new party can have the same name as the old one, if desired.
