So, you have a hard time convincing the kids that Santa is real? Windows Live Messenger has set up a way for your kids (with your help of course) to chat with "Santa" on Windows Live Messenger (you'll need to download the latest, but there is a link on the page). All you have to do is add Santa's messenger ID (northpole at live dot com) to your WLM contact list and then you can send messages to him and get a reply back. I suppose that this whole thing started because Santa had to become more tech savvy with the times, to be sure he could hack it when it comes to all the new-fangled gadgets the kiddies want these days. I did hear a rumor that Santa and Bill Gates go way back, which is how Santa easily got a spot in Microsoft's offering of holiday cheer, but it is largely unsubstantiated at this point. Heck, simply tell your kids that Santa knows Bill Gates (feel free to link to this post),I'll bet that will make them believe in him for sure. It just makes sense. There you go, a holiday KidHack for you.
