I'm talking about the icon within each forum. Just a very quick mock-up, based on the first page of posts:
The categorising system could use a bit of work (I'd maybe base it on the
BBC system - Business, Politics, Health, Education, Science/Nature, Technology, Entertainment - and then add a few more in, like Society, World Affairs, Americas, Europe, Opinion/Editorial), but it could be used well in conjuction with tags that might say a little more (for example, if the article his the AM[ericas] icon, then the tag might say [AM,
State Name]).
