I have used file savr before, and its not bad. I would assume that the file would be hosted for 6 months or so before termination, if it isnt paid for. Its really all about the user interface that you like when it comes to file hosting sites. Most of the time as long as it is a decent site there should be enough file storage and upload size for free for the average user. I actually own a free file hosting site
www.upload4ever.com. The first 50 signs up for a free membership and contacts the admin with the code blackhatworld, will get upgraded to a premium membership. I hope this doesnt get viewed as spam, It really isnt meant to be. I honestly like rapid share a lot, but the prices are pretty expensive. Another good one is
www.box.net. Anyway just thought that might help.
