Friends and conversations
Messenger is the in-game social window for your friend list and conversations. Select the intended character before opening an action; similar names can refer to different players.
Groups are separate
A friend entry is not Party or Guild membership. Use the Party window to manage your group and Party Finder to discover advertised parties. Guild Finder serves recruiting guilds.
Stay safe
Never share your account password in a message. For an in-game report, use Report Player with the character name and a clear description of what happened.
Friends and groups are different
Messenger keeps social contacts separate from the Party member list. Finding a friend does not automatically put them into your party. Send a party invitation and check acceptance when you want to adventure together.
Mail is useful for a named recipient and supported attachments; use its dedicated postal flow. Do not confuse a Messenger conversation with an item transfer.
