You've already aswered the question yourself. If you found securty issues someone else will. I doubt you are as skilled at hacking as others, so you can bet someone else will find your holes.

I would not recommend however, broadcasting your web address and the fact that you have security issues anyway. Much less a place were the level of technical achievment amoung it's users is so high. You may unwittingly be suggesting a challenge.

Cheers
