i have a suggestion for next version...
add an option where the script owner can choose to allow uploading to other servers....
like, when someone upload x.zip
the x.zip will be uploaded in the website and in other file sharing website
this other file sharing website is using the same script (XFS)
so that XFS owners can add each other's sites.
so:
i will be happy that my site is getting traffic
the other script owner will be happy that he's also getting a traffic
the uploader will be happy because he will be getting many links

something like traffic exchange between XFS owners...
this feature will be for XFS script only, you can make small panel in the admin where he simply add the URL of the other site and then in the main uploading page the user will see that his file will be uploaded here and there.
admin panel also offer a small space for the admin to write a small info about that other sharing site (like warning the uploader about the max size limit there)
admin panel can also offer up to (say 5) XFS sites
what do you think?
