The best way to get in contact with people who say they may or may not participate in the va2600 group is using IRC.
For those of you who know what IRC is, use irc.2600.net as the server and #va2600 for the channel.
For those of you who are not familiar with IRC you can just use mibbit to join the channel.
For those of you totally clueless, IRC stands for Internet Relay Chat. IRC is an internet chat service based on the model of people join a chat room and chat to several people at once, and the option exists to chat to just one individual using private messages.
