If at all possible, it would be nice to see a clear seperation between posts started in the current year in each of the categories from those started in preceeding years. Otherwise everyone tends to read down through the posts in each catagory and reply when they see something they would like to 'join in' with without realising they are responding to a post from, say, 6 years ago.

Although, I for one have noted that reserected threads often throw up some interesting views and ideas, so it is not to say that posts from previous years should not be reserrecte. But most often it is someone asking a question from years and years ago and ends with the monitor adivising that the thread was started some years ago.
