How to change your login password
To change your password, just click 'Peofile' in the sidebar menu.
From there, you can find 'Change password' option under the 'My Stuff' section.
You simply need to type in your old password for security and then type your new password in.
If you can't remember your old password, the best thing to do is log out and click the 'forgot password' link on the login page. This will allow you to enter your email address and receive a link to reset your password from there.
