Point your IRC client at irc.slashnet.org, and join the #robomonkdemo channel. Assuming that nothing has gone horribly, horribly wrong, you should see the current chatterbox content as new messages come in.
Is this out of date? It didn't work in Opera's IRC client, but Robomonk is still mentioned under "Interfaces for other protocols" in Other CB Clients.
I intend to download a free IRC client that allows Perl scripting (Gaim), and I'd like to write a plug-in to scrape the chatter of various rooms. I was hoping Perlmonks CB could be one of them.
