Phil, Welcome to OSM. I hope you like it here. Ask on the mailing list if you have any questions or need help with anything. There's a newbie session on irc://irc.oftc.net/#osm next Tuesday Meetings/20060808 which you might find helpful.
I'm pleased to hear you are interested in mapping some ski resorts. I did some parts of Ports du Soliel last season; worked out pretty well. See WikiProject Piste Maps for what has been done so far. 80n 01:52, 1 Aug 2006 (BST)
