We should indeed, I know some because of MySpace. But I think I will start one and people can post their birthdate (a few days in advance) and thus we all can give our kudos on the proper date.
@ Sixx: I don't celebrate Christmas either is called Day Saving Time
A friend of mine has that date too. Awful time to have a Birthday because it's sandwiched between Xmas and New Years. The only plus is that you're likely to be off work / school then.
Since I live in snow country I went to Arizona for the week between Christmas and New Years a few years ago and did something I had never done before on my birthday... had a picnic!
