Sky site
Carbon copy of the fox site, only with no spoilery information, so now us UK fans can go here for official info.

BBC site
Still has information for series one and two, support for this site from the BBC is now declining since they lost the right, it's now been shunted to the cult site, the place they put all the shows they've lost the rights to. Even though the BBC is supposedly a public service, they can't use excess resources on a show they no longer have the rights to. This would be seen as 'promotion'. The site does now have a msn messenger style chat thing called "connector".
