When I go to Preferences, it says that I've been on this site for "1 year, 12 months, 2 days".

And not 2 years which is required to get the achievement.

From what I understand, it doesn't count until it's the date that you registered. So, in your case, you should get the achievement on the 20th. :)

Your profile says... Joined: Thursday September 20th

The tracker that tells you how long you've been on the site isn't very accurate. You're not actually 2 years until the 20th, though. :)

You will get it when it actually switches over to 2 years. If I am not mistaken the site counts a month as 30 days so 12 months X 30 = only 360 days which means you would need 12 months and 5 days to be 2 years.

Ahh, okay. Thanks for clearing this up :) i never noticed it said 20th

Really? Thanks for the input, as I'm sure she missed the first three posts that told her that same thing within minutes of her posting. That's why she even responded to those posts with a bit of a "D'oh!" moment.
