Guests are welcome there.
Visiting the MOO is done by a telnet to a site which will provide your with a tiny fugue client which facilitates your tour. You will find yourself at a login screen where you will type grass for the login name and changeme as the password. A description of where you are, TapRoot, is the starting point of GrassRoots. This is a scroll feature that prevents loss of information. Just hit the Tab key when you want to see the next screen.
