I was a Compuserve subscriber for a long time starting sometime in the early eighties. Not sure exactly when I stopped using it entirely. I used it for various things and I was reasonably active in the shareware scene for a time which used CIS as their main member discussion forum. As I recall, CIS was also my gateway to Internet email for a time before I got my own email through my BBS (which became an ISP like other commercial BBSs at the time).
