USE APPROPRIATE SUBJECTS  
Your subject should be a broad description of what your problem/question/topic is. For example, don’t post a thread with just “HELP” or “QUICK QUESTION” in the subject. Doing this will be regarded as pure laziness and the thread will be promptly deleted. Also, do NOT use a different subject than what your thread is about, just to get attention. It will also be deleted.

its in the forum faq, read it
