how do you send a private message

PM's...

To your left, on the left side of your screen, there's a link
described as "CSN Email". Click on that.

At the bottom of the screen it takes you to, you'll see a few options.
Click on "write a new message"

When that screen opens, put the name of the poster you want
to send the message to, in the "To" box. If you have assigned any
"friends", you can use the drop-down menu to send to them,
otherwise just type the name in the box.

Give it a subject, write the letter, using as many expletives you can
think of, and send it off.

There. That's it. Now wait for the reply!

Bah-dah-bing; bah-dah-boom.
