Not to my knowledge, if there was I would highly question its reputability. This site has an age range of 14-39 to sign up (and there is the rare occasional 40, 41, or 42 year old or so that have been here a while). This age of 14 is for multiple reasons, including internet regulations and age requirements in many countries (the same way facebook and/or emails ask for a minimum age). Once they become 14, they can sign up that day. Also, we have something called a "teens only" section, that is granted to teens after time has shown they are eligible and are good contributors. The teen section is limited to those aged 14-22.
