Dan,
Most haven't logged in within the past month. Although, that can't be a measure of stickiness of the site. Keep in mind -- once you set a bill to "monthly recurring," you never have to log into the site again. You can continue recieving e-mails forever (which are sent out automatically every morning at 2). Some accounts do have this enabled.
If you have any other questions, let me know.
Shawn.
