Often, I will check Vassal to see who is online, or who has been playing a particular game over the past day or week, as I am always on the lookout for new opponents.
Is there any way to build in a contact mechanism - such as sending an email - to players? Perhaps this could be done without divulging the email - the message is sent to the Vassal server and then passed on to the player? The current message boards are poorly used and seldom checked, and often people who are in a room are either not really there, or even ghosts.
