Officer

In a Guild, an officer has the same powers as a leader except they are unable to disband the guild, change the guild's cape emblem or buy a Guild Hall. Other positions include the Guild's Leader and Members

They can:
 * Make announcements
 * Kick members out of the guild
 * Promote other members to officer
 * Invite players to the guild

For GvG battles, at least one officer or leader is required to start the match.
