i guess FF don't want us to get more money from sales. so only can buy one moth and one day premium.beacuse there are no rebills for uploader. then FF can earn more from downloader and uploader.
FF is very stingy never promotion for uploader. i don't like this filehost very much but have no choice,becuse i have sold more than 1500 premium for him. i can't give up this sucks filehost....sorry for my bad english.
