Most (if not all) of the information a user--or even a programmer--needs to know about participating in and building within a MOO is provided in the help system. That said, the help system is not that intuitive or well-organized, but the content is there.
The best way to get help within the MOO is to use the "help" command. Just typing "help" gives you a list of help topics as follows:

Type `help <topic>' for information on a particular topic, or `pick
<number>'
to follow a numbered link.
One good way to learn about how the MOO works and what you can do within
the MOO is to read through the help files in the following order:
Help introduction (type "help introduction")
Help characters
Help movement
Help communication
Help building
You can also use Help index for a list of commands indexed under various
headings. When you want help with any command, simply type help
followed by the command. For example, if you want help with the @dig
command listed when you type "help building", type "help @dig.
The introduction to the TAPPED IN MOO has a good selection of commands.
It might be a good idea to start with those and then move on to more
complex commands. The EDIT 797 MOO and TAPPED IN are both based on the
same MOO software so the commands are the same.
