Please send an email to cr4admin@globalspec.com and give your current user name and the new user name you would like. If you are a relatively new user to CR4, or if you don't have a lot of posts on CR4 then we will make the change. (That is the case for you, so it'll be no problem.)
FYI for anyone else who is interested in changing their user name, we do sometimes make exceptions for people who have an established presence on the site, but we handle them on a case-by-case basis. (We don't want to let well-established people change their identity whenever they feel like it... that would be confusing to everyone.)
