An Opinion...Manumatthew has the coolest profile on WikiAnswers.
If you are asking how to revert a question to a previous state, you can't. Normal users do not have that power granted to them. Only supervisors can revert questions to previous versions.
If someone is claiming to be you on their WikiAnswers profile, please contact WikiAnswers @ Answers.com (no spaces).
Your WikiAnswers profile will automatically stretch to fit the amount of content you wish to add.
Your profile is there so that other WikiAnswers users to get to know more about you. You can add what you like to do, what your favorite WikiAnswers categories are, etc. Basically, anything you can think of, you can add to your profile--even pictures!
As a Supervisor, my favorite WikiAnswers feature (though not available to regular contributors) would have to be the Batch Revert feature.The Batch Revert feature is a tool that allows Supervisors undo vandalism in answers caused by a single contributor (registered or not registered) in less than a minute. This feature can do anywhere from 1 to 1000 reverts at one time, so it is a definite favorite in combating vandal attacks.A profile page
"Batch revert" is a Supervisor-only tool to revert the answers of contributors in bulk at one time. This is useful if a contributor has placed multiple spam, vandalized, or nonsense answers to questions.
For now, you cannot relink a different picture to your WikiAnswers account profile picture, but if you used a social networking site such as Facebook, your profile picture on facebook will be the profile picture replacing the orange guy on your WikiAnswers page. For an example, I linked my Yahoo email to my WikiAnswers account, and the picture I have on Yahoo will be the picture on my WikiAnswers profile (check it out if you want).
The transition from "bio page" to "profile" was made to bring WikiAnswers more in-line with its parent website, Answers.com.
