I'd bet a nickel that Justin asked because he was trying to point out (or mock) that you misspelled Redhat -- which makes you seem FAR less employable. Knowing how to spell the OS you are supposed skilled on is probably the FIRST requirement of a job. Typos happen and are excusable. NOT realizing there was a typo when it's pointed out is not.
Attention to detail is vital for a tech support person.
First, I'm just pointing out your error, not mocking you for it. Second, it's not unrelated to you skills because in any business service, your technical ability is not the end all be all. Good Writing/Communication is probably the #1 skill that employers look for in tech support employees and contractors.
Breaking into a sophomoric fit on a forum when someone points out an error further shows that you are less employable that you would have us believe. I'm sorry if the truth hurts.
