See the tab "Visitor Messages"? Along side it, there's "About Me", "Statistics", "Friends", and "Contact Info". Click on "Contact Info", then choose "Send Private Message". That's how to PM somebody. I understand that there is nothing wrong in correcting somebody's spelling errors, but you don't have to shame them by posting it in public, since you might get a lot of backlash because the "Spelling Nazi" meme has been a very infamous and widely unaccepted one. So please take my advice, because I'm giving it to you as a friend bro. Thanks.
