Q:

What powers do chat room owners have?

The FAQ says:

Each room has owners, who can change various room settings and transfer ownership to other users.

And:

There are not a lot of responsibilites connected to room ownership, just a few extra permissions: The owner can add and remove RSS feeds being posted into the room, change room name and description, and similar things.

So what is the full extent of their powers?
Plus, besides revoking ownership, do moderators have any more chat room powers than a room owner?

A:

Most notably, they can move messages from the room into other rooms they have access to. Specifically, in this case, the target room is usually the Bin, effectively removing the message. The only other non-generic power they have is pinning messages, which is like super-starring.
