There are people that comes to the forum asking for Help, and there are people that comes to the forum just to see in what they can help;

It is true that nobody is forced to reply if one dislike or get anoyed about how some people poorly describe the problem when they are asking for help; but come on!, this is a forum and a community where you came expecting to share your experience, to ask and to be answered; so i think people that come to the forum should follow some basic rules that makes the visit pleasant; this also goes to the people that answer question; they have to be polite, if they dont know then dont invent the answer; if your are guessing then clearly say so in your post, etc.

Get anoyed for bad help asking is a normal nature for those who are expert in somthing; probably most you have seen this site: "How to ask question - The smart way":
