Wanted to bring a few things to your attention.
First, on the left side of the forum, it shows who's online. If you do not wish to be included in that list, edit your profile under Online Settings and check "Make Me Invisible."
Secondly, when you click on a person's profile, you're seeing their wall. There's a text box to post on their wall with an "Add Comment" button - this is not a private message. Anyone can see this.
If you want to send someone a message privately, click the Message button on their profile.
Any questions, just comment here.
