Not if you don't want it to.
You can make up a username.
If that username is available and falls within the Terms of Use for WikiAnswers, then yes, you can register the same username as you use elsewhere. When using the same username on more than one site though, it is a sensible precaution to make sure that you use different passwords for each site.
Unused usernames and passwords will not be posted here for everyone to use. Please sign in with an original username and password of your own.
You will need to request a username change. See the related question below to find out how to change your WikiAnswers username.

When you sign up for WikiAnswers, you are asked to choose your own username and password; you can personalize it from there during the sign-up process.(See the Related question on how to become a member of WikiAnswers.)

Check the answers to such questions to see if they are such a question.
Currently, there is no "friending" feature on WikiAnswers. However, every member of WikiAnswers has a bio page and a message board, and you can leave them messages if you like.
