So I talk a lot...
Is this enough reason to give me ownership on the chatroom? Is this ownership going to last until manual removal or something else?
See this post on Meta Stack Overflow – to make sure that an active room has an active owner, this may happen automatically.
Whether you do anything with that or not is up to you (being a room owner isn't really a huge responsibility). You could also appoint someone else as a room owner, if they are more inclined to be one.
Finally, you can also remove yourself from the owner list again if you want (just set yourself to "no special access" on the room's access control page). You might want to make some other regular user the owner before this, because if you don't, chances are that you'll get auto-appointed again pretty quickly.
Otherwise, congratulations on your "powers" :)
