How is this different to bugmenot? In fact, Bugmenot is easier to use because you can use the firefox extension to fill in the username/password fields.
They've decided to fight an uphill battle against an entrenched competitor, who offers an identical service. And aside from a slightly cleaner "professional white" interface, they don't seem to offer anything that Bugmenot doesn't. And BMN has a neat FF plugin, if you want to use it.
Color me confused. They need some compelling features to get users to change, and I'm not seeing any so far.
