HOW TO CONTACT ANOTHER STUDENT OR TEACHER?
You can send email to anyone in this community by going to his/her personal pages. When you sign into your account, you will see "Who's Online" on your right side bar. By clicking on any one of those students (who is also online at the same time you are online) in the Who's Online window, you can visit his/her personal pages. Once you are in another student's personal pages, you can click on "Contact" tab to initiate an email with personal message to that student.

WHEN TO CONTACT ANOTHER USER?
Before sending a personal message to anyone, you may want to take a moment to assess the quality of that message, give enough consideration to the privacy of the recipient of that message and evaluate whether this message is appropriate for the forum setup or personal message exchanges. As this community operates on a "honor" system, the ambient quality of this community is upheld by every individual in this community, that means everyone of us.

WHAT DOES HAPPEN WHEN YOU SEND PERSONAL MESSAGE?
When you send a personal message, you message is delivered to the email address registered by the recipient. Every student in this site has registered an email address at the time of signing in. If it is a valid email address, your email message will reach the intended student. The target recipient can read your message as a part of an email body, but he/she can't reply to that email. He/she has to sign in to this site to contact you through your personal pages as the way you did in the first place.
