What Screen Do I Go To To Add Another Screen Name?

Be more specific since ultimately the term 'screen name' has several connotations. It could be a pseudonym intended for internet communications as well as BBSs or simply an online identity. Thus, there are countless services or programs which involve the use of either one or possibly more screen names.

To give you an example, Yahoo messenger offers screen names or nicknames. To change this screen name you should click right on your Avatar so as to open your profile. Proceed to click on option 'Edit My Info'. Navigate to the nickname option, to click in that little round box you see next to the words "Use Another Name". You can obviously then type in any particular name you desire in that blank area you find below it. You can then click either "Preview" or "OK" button.
