Most sites, including CNET, permit you to use a pseudonym as your username and allow you to set your real name to private. Since you already chose your username to be your real name, I'll ask our community manager if he can change your username.
What would you like your username to be?
How can I post a comment under a pseudonym instead of my real name? There will always be someone who disagrees with anything that is said. I don't particularly like the idea of associating my real name with a contoversial topic. Those people could potentially find me if they want to.
