You can edit your profile by clicking on your name in the upper-right corner of the WordPress window and choosing “Edit My Profile”.
Some reasons you might need to edit your profile are:
- So that your full name shows up associated with your posts on your blog, or in any other blog you might be associated with (you can be associated with many different blogs.
- So that your preferred email address appears on your blog for contact purposes. Please note, however, that if you change your email address in your profile, and someone else wants to add you to THEIR blog, you will need to tell them what email address you have set in your profile (WordPress uses the email address for adding users to blogs).
