Could you write a script that would automatically turn it off on the 30th and back on on the 2nd so that you don't hav eto remember to do it by hand? Make it impossible for anyone who has their birthday set to 01/01/2000 or earlier (indicating that they are 12 years old or younger) to post or access the Forum without changing their birthdate first. Send everyone an email about the situation, then log the offenders out and have the system route them automatically to the panel to adjust their birthday when they log in. Require that their birth year be different from their join date year. Set the system up to default to keeping birthdays hidden.
