After some feedback that its sometimes difficult to work out whats read and not I have dropped some CSS in to make it a little easier ( hopefully! )
You can see this here:
the top two topics have been read whilst topics 3 ( White s1 Exige in Essex, Exige s 240 PP … and Exige spring ) are emboldened.
You can also see unread at the top ( new (3) )
If you visit the new section they are of course emboldened too
Hope that is of use
