Hi.
On aminet you can find two reasonably good solutions for hosting on an amiga. Realms which I think is an amiga specific mud, and a port of Envy which works well. I have used them both from time to time on my A1200.
Search
mudconnector for details of coding and building, they have good forums too.
If you want to run a mud for real ( ;-) ) then you would be better off forgetting the amiga and finding a linux host..... Oh by the way I just happen to run a free mud hosting server at
xtramud1.mud-dns.com where you can host any of the wide variety of linux flavour mud servers you like.
If you just want to learn a bit about area building, etc. then I could always do with the extra hands on my own mud Istari ( telnet to istari.mud-dns.com port 8990 )
