We have the emoticons operating in the chat area of the game
I was thinking that we could use them as signals, such as

= forward

= port

= starboard

= engage

= open the range

= your ship

= my ship
If we could have 3 or 4 seperate lists of signals, when you click on what ships you want, a preview page comes up and tells you which signal group your side is using
either that, or autosend an e-mail with the information
So a message might read
