As the subject says, BEFORE opening a new thread, first look if another similar has already been opened recently or in the sticky threads because, chances are the same issue has been already replied to elsewhere.
Failing to comply with this, will result the new duplicated thread being removed. If you see your post disappearing, it's because another thread on the same issues was already opened, so you were supposed to check that and, eventually, reply there.
The reason for doing this is precisely to help others finding help, which would be far more difficult if with multiple threads discussing the same issue.
