MUSH 101 Tutorial
As part of the AresMUSH mission of being more approachable to folks who are new to MUSHing, I created a MUSH 101 Tutorial. Other than the web portal section (which is obviously Ares-specific) I tried to keep it generic enough that it'll apply to other MU servers. Feel free to share it with your new players.
(The "Playing from the Web Portal" screencast is also a nice overview of what the portal can do, incidentally, for those who haven't really checked out Ares before.)
It's impossible to cover every aspect and variation of MU culture in a brief tutorial, but constructive suggestions of things that are missing/unclear are welcome.
