Me too! I used to be a paying customer (in 2005-2006 I think) and then when the login procedure changed to Yahoo, I could never figure out how it worked. I just stopped using it.

I never lost any image and I'm now a happy Smugmug user/customer (ha!), so I don't really care about that anymore -- but yes, the login process is important! Many users would rather change shop than put up with crazy login procedures.
