There are limitations without using an account, I'm afraid. You must have an account to post on the forums, edit questions, make improvements etc.
WikiAnswers operates using the wiki-concept. This means that people are able to ask, answer and edit questions without creating an account.
Yes, unregistered users can answer questions on WikiAnswers but only registered users are able to edit answers.
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.
Yes, you can submit a question without an account on WikiAnswers.
You can't. You can only edit it.
If you don't have an account, you cannot edit the answer. If you know the information is wrong and you want to edit it, just sign up for a WikiAnswers account. It's completely free, so it's worth a shot.
The only page that you can have on WikiAnswers is your Bio Page, which you automatically get and can edit at your leisure when you sign up for a WikiAnswers account.
You can't, you need to use your Facebook account to register an account on WikiAnswers.
Yes, you can.
No. At this point in time the only way to join WikiAnswers is by using a Facebook account.
No, you can ask and answer questions without having to have a WikiAnswers account.
It is not necessary to create an account to edit on WikiAnswers. Anyone can ask and answer questions. However, to use certain features such as changing the title of questions, you have to create an account.
