Before creating a topic to ask a question, search the appropriate forum(s) to see if it has been asked before. You'll be amazed how many things have been covered before. Also, you can search topic titles only, or post bodies as well. The more specific you are in your search terms, the more likely any hits will be what you're looking for (but if you're too specific, you might miss some relevant information). Searches run faster if you limit your search to topic titles and/or to specific forums and/or to specific posting usernames.
