I am coming from this question:
That deleted in minutes after answered and without a specific reason.
My problem is not the possible votes or something, but the right of the OP to delete the question in minutes if already answered.
For example, I could give a nice answer with my material (lets say copyrighted).. and the OP could just delete it and make my answer a proprietary software... And some days after I could not even find my answer in my profile. (need more than 10K point as I read).
So, the feature request, is to need at least a moderation attention for a OP to delete an answered question and in any case the member who wrote the answer has to be notified (Could not even imagine that doesn't even get a notification about his lost answer).
