Oh right! Cool!
I always remember reading about BBS back in the day, but being only a kid at the time, and not being able to afford a modem (in any case I wouldn't have been able to persuade my folks to let me use the phone), they were always a thing of wonder. I for one am very interested in the idea.
Here's an online BBS list I found, I'm sure there are others, perhaps you could upload your board to the list?
