This is a cool idea. Bruno Antunes took a MiST and turned it into an Amiga BBS!
Not only that, he wrote a massively detailed article on how to set it all up, with over 90 images and 3 videos. So presumably others can follow in his footsteps now. What an ingenious idea.
I'll have to connect to it this weekend and give it a spin with my A3000. =)
