First, go to the Sign in page located in the navigation menu of the WeDidIt website.
Then enter your login credentials. If you've forgotten or don't know your password, create a new password by pressing "forgot your password?".
As soon as you login successfully, you'll be shown a green success alert at the top of your page (i.e. "Successfully logged in").
At which point, you should see your username in the upper right corner of the page.
Click on your name to reveal the drop down menu, then select "My Ambassadors" to find your Ambassador page(s).
From this page, you can edit and view your personal ambassador page.
Similarly, once you've logged in, you can go straight to your Amabasador page URL, and notice an "edit" button underneath your profile image.
