Communication / Chat
After placing a flag on your map, its location can be shared with other players via the log window using a map link. Once sent in a message, the link can be accessed to open a map with the location marked with a flag.
With your map open, position your cursor at a location you wish to mark, then hold Ctrl and right-click that location.
* A red flag icon should appear on the map.
The text "<flag>" should now appear in the chat input bar. This is your map link. Type a message before or after this text if you so desire, then press enter.
If linked successfully, the map location and coordinates should appear in the log window.
Both you and the player you sent the map link to can click the link in the log window to open a map with the location marked by a red flag.
