I have sent you 1 merit point for this topic, once you receive another point, you will be able to see that you can send 1 point to a post of your choice. There is no restriction for newbie to send smerits if he owns them.
I don't want to control how you spent your merits, but I believe sending to a thread or post like OP is not a wise decision. His question has been asked many times and there are countless resources that can be found to answer him. Not to mention all of his previous posts were about bounties.
