If you’d rather not display your full name, to preserve your anonymity or for any other reason, you can choose to display a Nickname on your TypePad site instead of your first and last name.
First, while Editing Your Author Profile, fill in the Nickname you would like to use and save your profile.
Then, in the setup for Customizing Your About Page, check the box to display your Nickname (uncheck the box for Name) and click the “Save and Publish” button.
This will update your About Page to use your Nickname as the title of the page and also sets it so the rest of your site will display your Nickname wherever your author information is displayed.
After changing the Nickname setting, you can use the Publish button on the Design tab for the weblog to update your pages and feeds to use your Nickname.
