I have no idea what is going on in this thread, but just wanted to point out that TT is truly correct about the your/you're thing. It irks me also when people do it. Badly. But TT, haha, if I ever catch you typing "irregardless" on the forum, I'll become as annoyed about it as you are about contractions, and will say something untoward.
I never use that word. I use either "regardless" or "irrespective". As far as being a Grammarian, I normally don't go after people about spelling or grammar unless they profess to be some sort of academic or try to tout their education or intellectual superiority.
