I've found that people often won't allow multiple queuing, and I can't see why.
One reason for remotely queuing lots of files is because locally queuing doesn't place you in the real queue. It's a queue in your own computer but doesn't add you to the queue in the remote computer. After first waiting in your local queue for a request for a file to go out, when it finally does you may find yourself remotely queued at (like) #20 in line, and you've wasted your time queuing locally.
Is it not better to send all your requests to remotely queue in the other person's computer and get in line right away? If you don't you could be waiting till next Michelmas before you get the files. What harm does this multiple queuing do to the other person, so long as s/he has more than one upload slot made available to allow others to upload at the same time? Yet I have been Ignored for queuing multiple files and I've never understood why some react adversely to it. They appear to react to a queue for a dozen files as looking greedy or something, while it is nothing but ensuring that one is actually in the queue.
Is there something I am missing here, in that I'm causing harm? Or are some people reacting to a problem they imagine?
