One of the interesting things of WP 1.5 is the ability to rerun The_loop again in the same template. The main way to do this is to execute a rewind_posts(); after the_loop. This will reset the post counter so that you can make another loop round.
The slightly more interesting way to use multiple loops is to make use of query_posts(). What this basically does is reinitialises the query object. The clever thing about this function is that you can pass it parameters to make it a totally different query. We can, for example, make the second loop fetch back only posts in the 'shorts' category.
