Try placing your cursor over your name in the upper right of the web page (it should read, “Howdy, Tenacity”).
When the cursor is over your name, a drop down menu appears with Activity, Profile, Notifications, Messages, Forums and Settings appearing.
Place your cursor over the Settings listing. A side window should appear. Click on the General listing.
After a moment, the General page should open and your email address, that can only be seen by you, and two fields for Password appear.
If left blank, you password will not change.
If you enter a new password and again in the verify section and click save, that should change your password.
