Q:

How do I get the "edit" button (link) to appear on my profile page?

There is no "edit" button (link) on my profile page when I am logged in. I would like to correct an error and add an avatar.
How do I get the edit button to appear?

A:

Go to your profile page and then click on the "Edit Profile & Settings" tab:

Then you can upload an image and do all the other stuff you want to your profile.
You can get to your profile page by clicking on your image, reputation and badge count that appears at the top of every page when you are logged in:
