Just FYI, "irregardless" is not a word. The word you want is "regardless". Yes, I know that "irregardless" has now made it into dictionaries and whatnot, but that is just because it is misused so often. (Consider that dictionaries now consider "figuratively" to be a valid meaning for the word "literally" because that has also been misused so much.) "Irregardless" is the result of confusing "regardless" and "irrespective".
