First thing to know when MOOing is that it's not like IRC, where one can type directly the content of his/her babbling and see the output directly as well as other people connected to the same channel. In MOOs, one has to use quotes to talk:
"hi there

When using the quotes, the MOO will know you want to talk, and will display the content to other people in the room. If one doesn't use quotes, the server takes the input as commands, and will try to interpret them. Therefore, it is unfortunate, but the server won't care if you say hi to him, and will rudely answer: "I don't understand that" unless you use quotes, and it will then be prompted to other people.

When first connected, you arrive to Mauna Kea, which is the default room to which one connects at KccMOO. Since there are many rooms in which one might want to wander around, it would be nice to look around to see what is inside each of them, and see which exits exist in order to move around from room to room using those exits. Fortunately, there are such commands:
look

This is classified as a server command (because you don't want to talk to other people but to the server in order to request a description of the room you are at). Now, it's better you can see where you are, what and who is in the same room as you are, and what are the exits to other rooms. You can extend further this new power of lurking on objects or people. For instance, if Jim is listed in the room, or if a chair is sitting in the middle of the room, you can try:
look jim
look chair
You are now able to focus your observations to specific objects within a room. Good, now since you are at it, try look at yourself!

Mauna Kea is kool, but you might want to explore further this new realm you fell into. To do so, just type, the name of the exits that showed up when you type look.

Babbling is fun, but you might want to do body language as well just to perform a more complete and structured communication with your peers. Here is the way:
: waves his hands

Hence, to talk, use " and to emote use :
So far so good, who said MOO was desorienting at first?

Talking to everyone is good, but sometimes we might want to talk to someone in particular:
-jim hi to you only!
this time we replaced the quotes by - and the name of the person we want to talk to followed by our text. This option will help us out in discussions with many people to avoid chaos.

Also, it's always good to be able to talk privately...
whisper "hey body" to jim
page jim yohoo!
Those two above commands do almost the same thing, except that the first one will work ONLY for people being in the same room as you are while the page command works also for people who are at the other side of the MOO (in a different room).
Ok, but how do we know there are people in other rooms than the one we are at, and where are they?
@who
This will give you a listing of who is connected. It will be then easy to figure out if page is necessary or not.
You don't like paging? well, teleport yourself directly next to the person you would like to talk to (same room), by typing:
@join jim

Of course, you could have use the exits, but then good luck to find your way... May be later. However, note that some people do not link their room to the rest of the public MOO structure; therefore, using regular exits will lead to a fatal failure. But who cares about those guys making life too complicated, the main point is that when I look at other people, I see description, and when I look at my bellybutton, I don't see anything very original...
Let's fix that up!
@describe me as monkey brained, monkey headed!
Aaahhh feels more likely... well, feel free to choose a better one, it works for me, but may be not for you.

@gender spivak
Of course, one can replace spivak by male or female, but how boring.... oh well! you choose.

Remember, syntax is important on MOOs, one goofs and the server won't even try to work a way out to satisfy our needs (I hate this attitude but oh well, it's not getting paid either...). So we have to be careful for every command we type and check its correctness. A little painful at first, but after an hour it will feel like a breeze. Also, for all the above commands, one can always look up the true and holy help, which is more complete and will allow you to play around much more than just using this stupid help babling of mine...
You can always type:
help
help look
help @gender
help @describe
and whatever else comes to your creative mind. This time the server will try to output the help related the best to the key word you typed after help (but don't expect too much...)

There is much more to say about basic features, but people usually get bored if the help is too long (which I completely agree "get to the point already!"), so I better stop here. The rest, you can discover it by yourself, or better by asking other MOOers more experienced. It's much more fun to discover by ourselves rather than being fed like a piggy with routines and behaviors... so have fun!

Next chapter will be a similar help on building stuff. Yeah, moving around other's creation is kool, but how about us? we want our own as well!!

But give me a little while, the above lines exhausted me to faint, and I'll need some time to recover... Hey! working is good, but best to keep it for later ;)
