I`ve got MU Lifetime so I go for MU first & Then MF.
Do you get the annoying pop up from megaupload when you want to download a file?
megaupload for me. i downloaded only a few files from mediafire in my warez lifetime, as almost noone uploads there. no idea why... maybe that they delete warez files fast or something like that.
Good thing I'm not the only one. It is only now in the past, right?
