Hi,Ok... I'm sure there are loads of these requests floating about on the forum, but please humour a n00b :).I'm investigating the creation of a website for a friend for a community radio station.  There's a cool site he's seen:http://www.reachonair.com/On their tag cloud 'Show Genres', if you click on any genre you get an accordion open at that genre and the shows are given by 'date', 'title' and 'presenter'.Could I tag shows with K2 and them create some kind of accordion like this, or would it take some bespoke programming (alongside K2)?Thanks everyone.Dave.P.S.  What is the discussion extension used here?
