Traditionally, these forums are supposed to be about discussion. Posting a thread about how much you love a book/series doesn't really promote discussion, and is a good way to get it locked.
That being said, I read the first book and enjoyed it. However, I don't see the distinction between "the games" and "the plot." The games kind of were the plot to me. Unless you really just mean you like the romantic aspect of the book.
You can't, but a moderator can lock threads for you if you ask them to. They are usually the deviants with the ^ or $ symbols in front of their usernames.
