The reason I think that manhy hosts sharing files are not allowing uploads, and therefore many files we want to download are not available, is:

The number of upload slots you have is actually ONE LESS THAN THE NUMBER YOU SPECIFIED


ie IF YOU SET UPLOAD SLOTS TO ONE, NO ONE CAN UPLOAD.


I can't shout this loudly enough.

SET UPLOAD SLOTS TO AT LEAST TWO

unless you are a greedy git who won't share.

Can't believe that trivial errors like this and the download-resume error can bring a network to it's knees. Oh well.
