There was an open source project to run/emulate TSN/INN services. You could run the old software in Dosbox and connect to it. People rarely used it though, and people on the mailing list would try to start scheduling times for people to "meet" on the service just so it wasn't a ghost town.
The Sierra Network

Re: The Sierra Network
#12> The typical pattern on CompuServe or America Online was for customers to sign up with plenty of sober, practical reasons in mind or at least on the tongue — online news, online stock-market quotes, etc. — and then get inadvertently hooked on chat and games. The Sierra Network couldn’t pull the same bait and switch, for the simple reason that it lacked the same bait. To sign up for The Sierra Network, you had to be willing to say up-front that this was strictly an entertainment expense — strictly an indulgence, if you will. For some reason, many potential subscribers — even the ones with gigantic cable-television bills — seemed to find that a hard admission to make.
Tax deductibility of CompuServe and even AOL (regardless of whether 95% of your time was in chat or games) was a huge factor. Not to mention it allowed selling it to one's spouse or parents as more legitimate.
