TextSecure groups are fully egalitarian. Anyone may add members and no one may force an existing member to leave. There are no privileged members.
A group conversation persists locally on your own device unless you delete it, just like a normal conversation. The server does not store any records representing the group, so there's nothing to persist beyond the clients.
There is no plan to change these properties, afaik.
