There are still a few (emulated) ITS systems running online. In particular, there's UP, which you can SUPDUP into from your home machine, and even get an account on, if you ask nicely. Also, if you're interested in fiddling with ITS, and weren't around in The Good Old Days (as I was not), Björn Victor's ITS wiki (http://its.victor.se/wiki/ http://its.victor.se/wiki/) is an invaluable resource.
