In reply to BradleyWhite:
Just hook up with a partner who's climbed in winter before, show up in the Norries on January 30th or thereabouts, and join the queue... At that time of year you should very likely get some decent action in the white stuff, and if you can climb E1, you'll be off and running in no time.
Just bear in mind these two differences from rock:
1) After you've climbed it, rock does not generally fall down within the next 3 months. Ice/ snow generally does. BE PARANOID.
2) In belayed rock-climbing on a route where there's gear, falling off is quite often an option. In belayed ice-climbing on a route where there's gear, falling off is usually not an option. DON'T FALL OFF.
Enjoy!
