Anzio?

I have this program called "Anzio" that I downloaded some time ago! It was a free download and it also looked like a pretty interesting (and popular) program.

What the program does (as far as I know) is that it is some sort of telnet-related program. Telnet lets your computer talk to other computers.

I'm sure that I have used this program in the past - I just don't remember what I used it for?
