From your posts that I just viewed it is very difficult for any one to give you merits and what you need to do is to improve on them.  Posting in a very good English and both sentence and English writing laws a used do make you point clear to people and their may give you merits.
Another ways that you can get merits is to make posts that are of a great help for people.  Trying to educate people here and in turn you will be rewarded with merits point.
