When you mobilize your friends, their donations are tracked to you in two possible ways. 

1.  When you are logged into the site and send someone an email through the "mobilize your friends" page, the link in the email will connect that donation to you.  However, you must be logged in to the site for this to happen. 

2.  Alternatively, if you send someone an email through the "mobilize your friends page" when you are not logged into the website or if you send someone an email outside of the "mobilize your friends" page, the donor can input your name when they donate and then their donation will be linked to you.
