The community-building aspect of your post is commendable in my view, and it has what I call 'edge and appeal.'
Alas, I personally believe that posting one's DOB on the internet may have more downside potential than upside. Again, strictly my personal viewpoint - and each person's mileage may vary.
This Topic is called the "Birthday Board". If you would like to wish some a happy birthday or if its your birthday please post it here! We cann all wish each other happy birthday's here =). Also if your birthday is coming up please post.
