Comment 2 for bug 885739

On top of the improvements described above, it'd also be great to have a proper mapping between a queue entry and its uploader.

The main use for me would be for queuebot, so I can display:
"New package blah uploaded by person.ircname (universe) [old-version => new-version] (package sets)"

And then when accepted:
"Accepted package blah by audit.ircname"

Where audit.ircname would be the IRC nickname of the person accepting or rejecting the queue item and person.ircname would be the IRC nickname of the person who signed the package (as I guess LP can't always match the Changed-By with an LP account but can always match the GPG key with an LP account)
