There are many questions that are asked over and over so before you post one that may have been posted many times be sure to hit the search button at the top of the page and insert a word or two to search.

There is also the "Advanced Search" feature that is available on the same search menu, be sure to use it if you need it.

We don't want to discourage posting any relevant questions but if it's a common question you will probably find many answers that would serve you better than the one or two answers you get from a new post.
