You are one of many trying to find the answer but let me give you an advice. Go to the search engine and write Merit, mark the option to search in the subject only and arrange the results by the latest first.
You will find many threads and probably the right formula for you.
Keep in mind that merit itself has no value If you are breaking some of the rules here and get tagged or banned. Read the rules and the sticky threads in this section.
Great advice sir.
