My account turned 3 years old yesterday, but I don't have the achievement? :c

Did you try going to this page..

http://subeta.net/preferences.php?act=index?

That's the page you have to visit to get the achievement.

Have you visited your preferences?

Oh! Wtf! xD Thank you, I was going to so many random pages to get it and I didn't even think of that one! Thank all of you~ :3

Moving to the help forum since this isn't a bug.
