What will happen if I don’t care about the category during posting a question?

It is possible that you will be reported, and the question removed.\nIf it is reported, I believe that you will get a warning of some kind, and after you amass a certain number of warnings you are then perma-banned from Answers.

No.\n\nYou will also find that you are in violation of the Y! Answer community guidelines.

Like you, manners seems to be something that is lost on lot of people, which tells me that there is truly little self-respect in people, and this is sad indeed.  There are categories that allow them to be perverse in there questions and when they choose to not pick the right category, do not think your being mean to report it.  That is what keeps this Q&A forum as pleasant as possible for everyone.

Mostly category; hang out around polls & surveys most, next to movies and music... however, when the trolls and deviants come back, they make it worse and less fun, so I wind up doing some voting or move on to a different category. That bites.

YOu can only remove it if you remove it before it's under "voting", "resolved" etc. The other way is to ask stupid question and let others report you to remove that question. (possibly you are removed as well =P )

You should choose a category based on the people you want to answer your question, rather than the difficulty of the question.

you can remove the question whenever you want and about the email notification thing, I don't think there is a way to prevent notifications besides marking them as spam when they come in your inbox, I have searched for the same answer and cannot find the answer myself. Well, I hope this helps in some way.

To the right of your question, you will see options like delete, extend, vote, ect. just remove it. As for getting it entirely out of your profile I don't think you can do that. Don't worry, I've seen more embarrassing questions than yours. :)

You should wait until the question expires.  Questions are not easily "buried" here.  There are a few different ways for them to be found by others.  \n\nThey can be found via search, via category browsing and lastly, via user browsing.  So someone who liked one of your other questions or answers may find your unanswered question after clicking on your picture and viewing your profile.

The worst that can happen to someone on here is they get reported to Yahoo Answers which in return will get that question removed or they will suspend them from the site......

Is this really a question that diserves an answer???

U can delete the questions only in the open category only which r asked by u. Once the question is  resolved u cannot delete the question.

I suppose that you wouldn't want to change the question after somebody answered it because then they're answer wouldn't make sence or might mean something other than they intended.  If you make a mistake, you can delete the question and then make a new one.
