I didn't seen any post here about this, but few months ago the old JK2Files by Filefront back online.

Some mods hasnt uploaded yet, is why in some of them a "Re-Upload" button appears. They are calling on our community to help submit missed files that were previously hosted on GameFront / FileFront.
I already uploaded lot of mine i saved in JK2 days, i hope you guys can help too.
