Same! I didn't even know anything about telnet or programming. I was using Klik&Play or MultiMedia Fusion to make games, and some component supported TCP, so I opened a port using that and just for fun connected to it with a browser. Then I saw a request, so I used that the other way around on a real web server and it worked. Same thing with SMTP.
That's a program I haven't heard of in a long time. I wonder if you can still get it running in a VM since it was just shareware with a nag screen if you said you were using it for "educational purposes"
