What user have downloaded ???

[ACiD]

ioShowlog by mr_F will allow you to issue a SITE command that will show you the most recently downloaded files, sorted or shown by several different parameters.

I know thats not the way you described the script, but this is the only script i know of that offers similar functionality.

something like ioBanana, ioA, or something else might offer a command that will do what you want, but i simply don't know because i don't use those scripts.
