For many people who may be new and are joining each day....there is a blue bar above underneath your sign in name. One of them is a search button, where you may find a topic that answers your specific question that may have already been asked/replied to.
One thing I try to be mindful of as a regular here is to keep my post titles to the point, so it will be an easy find for new people. Plus, it helps save server space. Hope that helps.
