The two main reasons for contributors to delete an answer on WikiAnswers and save it are to remove "bad" answers or to vandalize.
Contributors can and may delete answers; however, this is discouraged unless the answer is bad (i.e. vandalism, etc). Like most of the more powerful tools, this requires users to sign in.
No, they did not.
To delete an answer, you go to the question, click edit, remove the answer and click save
You cannot delete the 'My Contributions page'. You cannot delete the Contributors tab when you write an answer, either. Both of those remain permanent, and cannot and will not be deleted.
Contributors on WikiAnswers cannot delete answers to questions. You may edit a question to improve it but cannot remove an existing answer completely. If you believe an answer has nothing to do with the question being asked then go click the flag/report button in the top right corner of the question and mark it for review.
Questions on WikiAnswers can not be deleted by regular contributors. Supervisors can trash questions into a catchall category, but only advanced supervisors can permanently delete questions off the site.
As many as you wish. See WikiAnswers Top contributors page to see the list of top answerers.Special:TopFarmers
You may want to ask this on Yahoo Answers (or better yet stay here and ask and answer questions on WikiAnswers instead of Yahoo Answers :-) I would guess that since you are the one who wrote the answer Yahoo is giving you the ability to edit or delete it, but is not giving you the ability to edit or delete other people's answers.
We don't but a better question is why would you not delete or report them like you are supposed to
Only Supervisors or Staff can delete questions from WikiAnswers or Answers dot com. Primarily, questions that violate the terms of use or rules of the site are the only ones deleted.
There are a number of us here that are WikiAnswers Supervisors- when we find those, we delete them- and sometimes, we delete the vandal leaving those answers. If you have a question that has been vandalized, you can improve the answer by deleting that response, save it, and it goes back to the "to be answered" pile.
