they purposely make the sites non-clickable, to foil referral detection of their own site I imagine. you prolly captured the url you wanted to access in the first place, so just note the id and password (always identical??) and plug the url back in to your browser and GO.

and what do they gain? well, it could be a scam; or they could be after Fame and Fortune (Google started in a dorm room, you'll recall).

p.s. - you should check out their FAQ.
