There are various sites to look at for Christmas fun.
The North Pole site includes ideas for fun activities, easy recipes, ideas for parents, and a section for teachers: www.northpole.com/
The Elf Yourself site offers a download in which you can add face photos of people to the dancing elves. The site is only available in the holiday season; when the site is inactive, OfficeMax provides the website with a placeholder image informing viewers that "the elves have left the building".
The Norad Santa tracking site allows you to follow Santa as he makes deliveries on Christmas Eve. The site is only active from 1st December: www.noradsanta.org

I was always making notes on scraps of paper about tips and facts I'd read in books and magazines, seen on the Internet or on TV. So this is my paperless filing system for all those bits of information I want to access easily. (Please note: I live in the UK, so any financial or legal information relates only to the UK.)
