I did not start out to make an LGBT server, this was more of a coding and deployment exercise. However, I did not realize until much later that in 1993 there was no exclusively LGBT Internet chat site. Among some other alternatives was Lintilla an adult chat site, which had one gay chat server on port 5002. For example: IRC - Internet Relay Chat was huge, there were some MUDs - MultiUser Dungeons (MOOs) and other off shoots, but they had their detractors, like IRC could display every person's location, and the users were not exclusively LGBT, MUDs had similar issues including a more difficult user interface and they were designed for game play which intrinsically spread users over their virtual landscape and made conversation and community more difficult.
Let me say that there were many places on the old pre-forprofit Internet where people could meet to chat who were gay, lesbian, bisexual and transgender.
