Although we changed it less than 6 months ago, and despite it being a big improvement over the old home page, we haven't been 100% happy with our new home/login page. There wasn't enough information "above the fold" for new customers looking to signup.
So we've been experimenting with some layout changes that we've currently put on our beta server at http://www.fastmail.fm/beta/.
For existing customers, there's little to no difference. The login box is still near the top on the right hand side. For new customers though, we believe this page contains more relevant information in a more concise form.
