Kuba. How do you know you have messages? You can't send messages and no one can send to you until you have a few more posts. There is nothing anyone is going to tell you to save your life, other than relax. You won't die soon. Relax.
By the way folks and I mean the newbies, if you took the time to read the threads below this one you'd be able to figure out how things work. These same questions get asked weekly and get answered AGAIN. Read and learn from others before you.
