I remember it being 10th October 2010, but it has suddenly chsnged to 10-11-10... anyone know what happened?
Well, I'm not mistaken. Here in my laptop it's saying: "Join Date 10-11-2010" 10-11-2010 is Oct 11th 2010 right? Machazo said he joined 10-10-2010, Oct 10th 2010, right? This is odd.
Well, for Machazo and myself now is 01:32 AM. Check mine then, I joined here Jully 20th 2011, the Friendship Day. I remember it clearly.
I think this is some kind of prank pulled by staff (like "Isntitpretty"?). Since today is 11-11-2011, somebody thought it was funny to make everyone's join date 10-10-2010.
I think Amaury may be right, time zones might affect it. For example, October 10th for me might be October 11th in, say, England.
The most likely explanation is that going out of DST affected it. Either that or you just remembered it wrong.
This is probably it. Remember on my birthday how when Bueno posted that thread wishing me happy birthday, there was the on-running joke of how it was my birthday where I am, but not where he was (at the time). (Or as we liked to call it... I'm in the future.) It's probably the same matter as this I would think, or at least similar.
