I've worked out a set of fields (for a program) for such a site, and have worked out a new Dir structure too- as the Aminet one is a bit archaic, and hard to understand. The structure I came up with was used for the MDC Labs pages (although the Game subdirs have been culled down a bit :/ ). http://mdc.morphos.net/index.php?mode=labs
I've also got a large list of useful programs for MOS, including 68k ones (not sure if all the 68k ones work though)- as we need to provide all, software that works on MOS, not just MOS native ones!
Mail me if you want anything! :)
