Change your username: IF it's working (and I've seen a user I'm familiar with here that's change their account name several times in recent weeks, but it doesn't seem to be working today (at least not for me).
Change YA username:
1. Click on your account name in the upper right of your screen, just below the links for “Answers Home” and “Notifications”.
2. On the landing page, click “Edit Preferences” beside your avatar in the upper part of the page.
3. On the next page, you’ll see My Profile and a thumbnail of your avatar, click the “edit” link beside that.
4. Typically a text box would open and give you the option to select a YA nickname or change your avatar, however at present you’re taken to your Yahoo profile page Personal Info. That page isn’t allowing any of the text fields to be changed at the moment, but it did open a box to select a file to upload for my avatar, when I clicked on my avatar photo. Not sure if it would actually allow me to change my avatar or not though.
