www.dropbox.com
About 10 of us in the North are already onto Dropbox. Its FREE to sign up and very easy to use. Creates a folder on your computer where you can simply chuck photos and they automatically become available for everyone who is part of that group.
Works very well and makes sharing large amounts of pictures very easy.
If anyone signs up in the North let me know here and I can share our "windsurfing" folder with you.
Im certainly not promoting we dont post on the forum, this is very important for the life of our sport, but posting hundreds of pictures on the forum can be time consuming - not of interest to everyone. In dropbox it takes about 6 seconds and whoever wants a particular photo can copy it.
Im loving it, and I know a few others up here are fans also... very good thing and free
