I have a Megaupload Lifetime Platinum account and I will not be using anywhere near the space they provide. So you may use my account to upload and store your files on a permanent basis, with only a couple of restrictions. First of all, uploads must follow the Megaupload Terms of Service, and secondly your uploads may not be any larger than 100MB. If I see files that are larger than 100MB in my account, they will be deleted and your perma-link will be lost.
