Well errr yahoo giving bigger space/bigger attachment sizes doesn't make me send any more if that's where you're getting at,
but yes I do e-mail lots of photos to my family, mostly to my dad who lives on the other side of the globe but I do have an online photo storage where people can go and check ie. our photos from our trip to California so there's no need to e-mail those to anyone.
Yahoo giving more space just helps me getting more behind on my clicks, that's all

P.S. Edited the word live to like in the title
