I ran one in the 90s for a couple years. I was 15. I had two lines at 16.8kbps. 100 megabyte HD, which was enough to hold a giant archive of Amiga downloads. It was fun, lots of local folks on there and we'd meet up in person sometimes too. Felt like I knew everyone in town who was into computers as much as I was. Especially the Amiga people.
