Web Site Features

First, make sure the feature is activated, Go to your profile (MEMBER FUNCTIONS, Edit Profile.) At the bottom of the page, there is a check box for Instant Messaging. Check it.
Now you are ready to go. When others are online, you will see their names in the "Who's Online Now" box. Your IM chat box needs to be active. It appears at the bottom right of your screen. If it is not there, go to "MEMBER FUNCTIONS." Find "Turn on IM," click on it.
Now you are ready to chat. If your chat box is not expanded (i.e., only the one line indicating how many members currently online appears), click on the up arrow to expand. Your name will appear on top, and other members' names will be below. Click on the name of the person you wish to chat with, and then on Chat. A Private Chat section will then open up on your screen. Type your message as instructed, then hit enter.
Hopefully these instructions will tell you all you need to know. A more detailed description on how to use this feature can be accessed by hitting "?" next to "Search for Members" in the chat box.
