How does this work?? Provide one file, at most 100 mb and upload it to the server. Then you will recieve a random file that someone (or you) uploaded before. The number of files on the server is always constant, so after you recieve your file it will be removed from the server. You can't upload the same file twice. WARNING: at the moment there is no filter on the files you can upload, meaning you could recieve anything, including malware.
