Internet Relay Chat
Internet Relay Chat (IRC) is a live, instant messaging system that requires no registration. Much of the time there is someone into NVC on an IRC channel (server: irc.freenode.net, channel: #NVC). There's standalone software for IRC, or you can just use the web interface here - if you would like to get in contact with others live, just click "Chat!"
Standalone IRC software we recommend for different systems:
- Mac - Colloquy
- Windows - mIRC, Trillian,
- Linux - kvirc, ksirc
Note: You might find that clicking on Chat doesn't work as well as other methods suggested here. If you use the free open source and "Best of Class" Firefox web browser, you might prefer the free open source Chatzilla plugin. It opens a new window leaving your browser window as-is, and it has many helpful features.
