U'm so my bud tried to make an account for CYS.com. He was born in 2003 and to get to 2003 he had to click, and click, and click, and click to reach his birthday. So it really isn't a glitch but usually on the calendar's if you click on the year it brings you to a tab with all the years which wasn't working.
Yeah, that's an extension feature. The extention switches the date picker to the browser's native ‹input type="date"›, which is better but didn't exist back when the site was built. (And it still isn't supported by all browsers.)
Okay, It at least better than what was in place before. Thanks!
