I'd also like to point out that we also have an option available where you can bump up your maximum simfile size on your account. It is a lifetime membership, your account filesize limit is increased to 30MB per simfile, and it's only ten bucks. So, if you want to support Bemanistyle, and be able to upload high quality simfiles with excellent quality audio, or just extremely long simfiles, you might want to consider this, rather than an external hosting option.
