If enough people ask about how to delete questions, do you think Yahoo will change it so that we can delete our questions?

No, it's doubtful. They don't seem to reverse decisions very often, and there is rationale behind not allowing users to delete questions after they are answered.

A lot of users complained that askers would delete their questions soon after someone answered it, and the answerers would never get credit for their work. This was especially prevalent with homework questions, so that the student can "destroy" the evidence of them asking for help, or asking for their homework done for them, rather.

This is Yahoo ANSWERS - and that means that the answers are more important than the questions. If you delete a question which has received an answer you also delete the answer - and that is what you are no longer allowed to do.

If I have made the effort to post an answer to your question, why should you then be able to delete my answer without my permission?

That is up to Yahoo!

Maybe making a suggestion on the new suggestion board would be worth while. If enough users complain about not having the option to delete their questions who knows what might happen.

Probably not Yahoo doesn't have our interests In mind when they make their decisions, as long as they make money tough stuff for us.

no there no way yahoo will do that.

you just need to be more careful. what you ask.
