email button?

I have to made a announcement for my class that requires members send emails to the classleader. And i dont know, except me, another members dont see email button in their contact list. That's mean i'm the only person who can send mail to members and i'm the only person can recive mail from members.
These are 2 pictures illustrate for my ideas. I created a normal account and login as a member. I use that account to view 2 different profiles. Above picture is my contact and below in a member contact, Please help me. This is really emergency.
Thanks for your help.

Hi, your title not being specific and therefore not facilitating research via the search option, I'm not answering (nor is any other member ) until you change your title to a more specific one, related to your problem

Why do we ask you to use explicit titles

Code:

The forum's search engine bases its research on keywords found in [b]topic titles[/b].

When you do a research, do you use "help", "urgent", "problem", "SOS" or "question" as keywords to look for topics about your problem/question?

Certainly not!  So this is why it is important to use titles [b]related to your problem/question[/b].  Doing this makes the researches much easier for visitors who use the search engine to get an answer to their question.

Thanks for your understanding.

Cordially
