Checking a Player's Software Version

To see what version of GridGammon software a player is running, select the player in the Lobby, then Option-click the Info toolbar icon. The player's version will be displayed in the Lobby chat (people running GridGammon on a Mac should be MAC-nnn, where nnn is a 3 digit number, for Windows, it will say WINDOWS-nnn).

You can also type "/version <player>" in the Lobby chat to retrieve the player's version info.
