Each BBS had its unique ANSI. A room for files, another for XXX content, one for messages to other members. Some felt lively and bustling. Others felt like walking into a quiet dark cave. You never really knew what you might find.
My dad ran a small Wildcat BBS in the late '80s. I still have all of his files. Probably a couple hundred megs in total. Not sure how he picked that software. He had every BBS software you could imagine. He had a friend at the time that he would trade floppies with. One day his friend brought over a copy of Leisure Suit Larry. I was really intrigued by a game that I had to leave the room when they played. Everything was a bit seedy back then. You ever seen CGA porn that runs from a .COM executable you downloaded on a BBS? It might be porn. It might also destroy your entire computer. 1980s equivalent of a risky click.
