I used to run a BBS using MaxsBBS. Completely different to the likes of AmiExpress, not as professional but way more fun I thought.
We had all kinds of tricks and plug ins to get things like File ID Diz to appear in listings, have 2 digit menu codes and such. You can get it and a massive amount of doors for it on Aminet. There was a guy called Nikki Murkett who released a revised version around about 1996 I think with a few extra features.
