I never got WWIV to run. I ordered it through a shareware disk service in the 80s. I was so excited to have my own BBS, but the software didn't work at all on my Mac plus. I have no idea why. Eventually I used Hermes.
I never found Hermes to be buggy, but I was using versions prior to any TCP/IP support, that's for sure. I wrote a few externals for it. I really liked it.
There was also a BBS system called "Mansion" that I remember seeing. It had some really interesting ideas on how a BBS should work, but I can't remember any details. I didn't end up using it because it lacked some pretty expected feature by BBS uses.
