I tried it with a birthday less than 10 and it told me I wasn't old enough. Then when I tried it again to change the birthday, it didn't give me a choice to change it and it told me that I wasn't old enough still. It has to remember it via a session or a cookie. I'm assuming a cookie because when I clicked on HELP/MY COOKIES UTILITY/EXPIRE COOKIES, it showed the birthday thing again. I then entered my correct birthday and it worked fine.
I also went in and told it that I was under 10 and when it told me I am too young, it gave me a "BACK" link to go back to the birthday enter page. Even though I entered the correct birthday, it still told me that I am too young so it must not be clearing the info when clicking on "BACK".
If it was me and that bothered me, I would just add the expire cookies button to the register.php template that comes up telling you that you aren't old enough and add the caption "Re-enter Birthday" or something like that if it is possible or add a button that takes them to the expire cookies page.
