Nevermind - this has been cleared up via the IRC channel.
Account Manager > Server Management (on the left menu) > Scroll to the bottom to add server message.
Works like a charm - thanks. ;)
*edit* - color codes for cod4 are supported, as well.
So, I'm not seeing where this would be applied. I do, however, see the screen to add a custom greeting per GUID, but I'd like this greeting to be applicable to our server. So, as soon as one connects, it displays the message "Welcome %name%, to the [KwP] server." or something to that effect. Ideas?
