I also remember the MausNet. This was a German speaking counterpart so to speak. Interestingly, I remember it from my Atari days, even though it was initially a Apple network (Münster Apple User Service).
Greetings from the past! Was on KA2 back then, Minnie was such a nice user experience. Will always remember the groups Pascal, Oberlehrer and Allohol =;-D
