No, to register with WikiAnswers is free.
You don't have to register for WikiAnswers if you don't want to.

It depends on the type of register. Some do others do not. For instance Wikianswers has a register of user names but very few users have given their address.
The minimum age is 13, same as Facebook and WikiAnswers.
You can create questions, and answer them with being just a guest, however, there are limitations such as editing questions, editing answers etc., otherwise one would need an e-mail to register on WikiAnswers.
It should be to the left, below the "Ask" green bar and the "Answer" blue bar.
The best use of this site is to ask or answer questions, which is what WikiAnswers is all about. To get more out of it, you might want to register. It only takes a moment to register and sign in. Signed in users can do more, and they can use their watchlist to see when their questions are answered. They can also watch topics of interest to them. Everyone has a niche, and with so many topics, they are likely to find one here at WikiAnswers.
Might be less annoying if you register to use the site. Need specifics on what bothers you to answer
