BigBrother.com Has Been Somewhat Attended To.
 

At the bottom of the bigbrother.com page it now says 'Visit BigBrother on Channel 5' It said until very recently 'Visit bigbrotherauditions.com for more details'.

This means the website is clearly not forgotten and as it still says 'coming soon' so its likely that it will have live streaming for normal BB/some extra thing on there for BB12.
