You have to be 13 years or older to sign up for an account. You also need to have a Facebook account to sign up.
Signing up for an account allows you to use more advanced features on WikiAnswers. You can't edit questions without signing up for an account because WikiAnswers wants you to sign up and contribute to WikiAnswers. Think of not signing up as a demo version of WikiAnswers - you can use some of the features of WikiAnswers, just to get a feel for WikiAnswers, and we give you just enough so you can figure out how everything works on WikiAnswers. Signing up for your account gives you all the standard features on WikiAnswers that you didn't get in your 'demo' version of WikiAnswers. The standard features include editing, while the demo version does not. Signing up for WikiAnswers is completely free, so signing up for WikiAnswers will allow you to edit questions. The other main reason is because of vandalism. 90% of vandalism occurs from unregistered users on WikiAnswers, so giving unregistered users the power to edit a question could potentially give them the power to wipe out every answer on WikiAnswers. That is why you must sign up for an account to edit.
You just sign up for a WikiAnswers account, and once you have signed up, you are able to participate in The Community Forum.
No. Anyone signing up for WikiAnswers who is under 13 is doing so contrary to the TOU.
