Button on user profile page to send email I think this is pretty simple, but I don't know what's the best way to achieve this.

This is what I need:


Add a button on each user profile page. When another user clicks on the button, it opens a form (in a popup window would be great) to write the message. The email should be sent to the user of the profile page we are seeing. 


If it's not possible to add a form, I just need a "mailto:useremail" so when i click the button opens the outlook our gmail, wtv.

How can I do this? Is there a simple way?

Thank you!
To get what you want, you need to modify the template user, to do this you need to follow the next steps:


Find the file called user-profile.tpl it is in the module user modules\user (NOT inside sites/all/modules).
Once you found it, open it, and you should see at the end of the file something like this:



  print render($user_profile);



Now copy and paste this line of code inside php tags: 



  $usr = user_load(arg(1));
  
  echo 'mail.'?Subject=textyouwant"
  target="_blank">Send Mail';


That should work !
