To invite other players to be friends in the game: go to your Account panel, then the Friends tab, and type their name in the "Add a Friend" field and click the button. They will receive a friend request, which they can either accept or block.
If you block someone's friend request, they cannot submit another friend request. However, you can send them a friend request, and they will have the option to accept or block it.
Create a pack in the Friends tab of your Account panel, then add other players as members. Those players wil receive a pack request, which they can either accept or decline.
You can then send group messages to everyone in your pack, which is helpful for scheduling multiplayer games.
You can remove members from your pack at any time.
You can send in-game messages to other players in the Messages tab of your Accounts panel. The receipient will get a notification alert if they are currently playing the game, or a yellow envelope-icon on their Accounts button and Messages tab if they have unread messages awaiting them.
Note: Message notifications should appear within 90 seconds, but apparently it can take longer in some situations.
You can delete messages you have received, but you cannot delete messages that you have sent. This is a limitation of the current account. We apologize for the inconvenience.
