Are you refering to the search results or the downld window. On the search results, those no.'s under the
# column represent how many other people have that same copy of the file that your particular search was able to find. In the downld window it will show how many hosts (other people) you're downlding from. It will show the downld speed in KB per sec, & estimated time left to downld.
If you're in a waiting list then yes, it means the uploader is busy & you are in a waiting line. You might be 2nd or 3rd in the waiting list, etc.
