|The Social Menu is how you access controls for other players. It contains a search bar, shows pending invitations, and lists your friends. You can search any player by name, even if they are offline.
Sending invites to players is done through their Player Portrait. Hovering your mouse over a Player Portrait opens a flyout menu with buttons to do things like invite the player to a Group, inviting them to your Company, sending them a Whisper (private chat message), adding them as a Friend, or Muting or Blocking their communications.
Anywhere Player Portraits appear offer the same flyout. This includes chat messages, the Nearby Players list, and your Company Roster.
