Yes, the very first "Internet" application is still around. Once upon a time, you could dial over the phone to a BBS server and "talk" with other folks who were dialed in. You still can.
But I don't participate myself. I am trying to get one of my friends who does to log off long enough to write something for me. If you want to volunteer (or to volunteer someone else who susceptible to blandishments like a lifetime supply of Virtual Chocolate) please email me.
