What privileges do I have as an Account Admins beyond those of a Host?

Account Admins get access to a web-based admin panel that Hosts cannot see.

 

This allows Account Admins to add/remove other account admins, create/close guilds, appoint/reassign Hosts, as well as see a list of all guilds across their account including who hosts each one and who the members of each are.

 

Account Admins can also change the logo and header image for any guild they manage
