Are you retarded? Obviously he knows how to read if he was literate enough to locate these forums through either a Google search, or navigation of the Call of Duty website. Without the reading ability that you claim that he doesn't have, he wouldn't have determined that this forum was even a Call of Duty related forum. So, taking that into account, he will post his Call of Duty related question, in the hopes that someone is decent enough to provide him with a suitable answer to adress his predicament. Also, let's not forget that reading and writing go hand-in-hand. If you know how to write, there's a good chance you know how to read as well. Sure, there were some grammatical errors in his statement, but we're all humans who make mistakes on a regular basis.
So, in short, this user clearly knows how to read. You, on the other hand, forgot to end your sentence with a period.
