I go on "Edit Profile":
Once in my profile, I scroll down to the "Password" tab. I then click on "Change your password" :
I am then redirected to this page :
I click on "Send", and an e-mail will be sent to me.
If I can't find the email in my inbox, I check my Spam/Junk mail. Once I find the mail I click on "Reset my password".
Once my new password has been registered, I login to the site with my new info.
