You can report them to have them moved to request? Don't know if that's allowed. Like @HBG said. Chances are these people are no longer active en asking for a re-up in said thread is just a waste cuz no one is going to read that
Problem is that there's a lot of posts that are old, some of these users aren't active anymore. You'd have to either pm active ppl who have the track to upload, make a request thread for the tracks you want or find them from other sources.
Is there anyway we can pull together and get broken Zippyshare links back up with Mediafire?
