Here's my annual poll about such things. The options are a paper card (with either BEARS or a picture of London on), or nothing. This is because I never, ever get round to sending e-cards. My main purpose in sending Christmas cards is to send and receive proof that my Invisible Internet Friends are real - which I don't get from an e-card.
Do you want a Christmas card from me this year?
Yes please.

The following partners, children, housemates and pets should be acknowledged on the card:
My address is:
The same as it has been for many years so I'm sure you have it.
7(58.3%)
The same as last year but I'll give it again in case you can't find it.
3(25.0%)
Different from last year and I'll give it to you in a screened comment.

All comments are screened so you can leave your address below. Please do it a.s.a.p. so the cards have some chance of getting to you :)
Also, feel free to receive a card from me without feeling obliged to send one back. I send cards because I like to do it, not because you must! Although if you do want to send me something, here's my address.
