There are three ways to do this. First, on the left hand bottom of the menu there is a “Who’s Online” box which tells you how many users are online. It will also indicate you have private messages waiting for you. Secondly, if you click on the button labeled “Members List” it will display an alphabetical listing of all members. At the top it will indicate those currently logged onto the site. You can click on their names to view their profiles or send them a private message. Thirdly, when you visit the forum, at the very bottom it will indicate who is currently using the forum.
