I have checked with the grammar website, and those informations are pretty bad and poor. You should use some grammar check websites before posting things as your english is not fluent, probably your second language which means that you will make mistakes.
@ogah. I don't think you're asking the right people to check it. I'm sure if you Googled you'd find a forum where you could ask for advice. How about http://www.theadminzone.com/? They may point you in the right direction. They have a Forum where you could post this as well.
