Currently the forums are running on an icon scheme I put together that's a slight modification to the original theme. The only thing I changed was the little icons you get to the left of a topic that tell you whether there are new posts or not. I made it so that popular topics use the same icon as ordinary ones which makes good sense. Before that popular ones had gold icons. Now it's just simple grey for no news, blue if there are new posts.
At the time I also made a set with blue for no new posts, and gold when there are new posts. Both looked pretty nice, I was wondering what people think. If you like we can try the blue / gold set again, or just stick with this set. I can make them up in any colour you like so suggestions please!
