You didn't assume I was trolling? Well, I appreciate that but, under what circumstance could me wishing you a happy birthday even be considered trolling?
I understand and respect the desire to preserve your privacy on the internet. The point of my first comment was that publishing your birthday was optional. It's been so long since I registered, I don't even remember whether providing a birthday is required as part of the registration process. But I do know that you're not required to share that info: if you leave those boxes unchecked under Account Settings, not even the mods can see what it is. So, if you didn't want anybody to know your real birthday... you could have simply kept it to yourself.
In any case, you're welcome for the thanks.
