If you look at the heading line at the top of each column, the line that has:
Thread/Thread Starter, Last Post, Replies, views, Forum
you can click on these head lines and it will organize each according to the info in that column, I used to use the replies to put the post in order to bring up post with 0 replies, it make it much easier to keep track of post, almost all windows based programs has this feature, even outlook Express E-mail, as does most forums like this one that Bob posted a screen shot of. If you go to that forum and click on the header right where it says "replies" it will list the replies in order of the most to the least, click again it will reverse the order from the least to the most.
This would be nice to have on every page that is a list of post or forums.
