Okay, this one is going down on my I-don't-get-it list. I was signing up for a log in for AllRecipes.com and this disclaimer shows up on the bottom:
I am age 13 or older and therefore may register or submit personal information to Allrecipes, as compliant to the Children's Online Privacy Protection Act of 1998.
I can't think of ONE reason why you need to be over 13 to post a recipe... I suppose they don't want pedophiles posting inappropriate stuff to their website? :S
That said, you can save your recipes on their site. You should take a look. ;)
