Please note that my initial upload of this file may be slower than everyone likes. I can't help that. I am not firewalled or deliberately slowing uploads or seeding a gazillion files. It's just that Australian ISP's are among the most pathetic in the world for uploading. If it's going to bug you that it takes a while to download it while it's only me seeding, then don't do it. Don't say you weren't warned. I will seed while there are people downloading this (assuming anyone wants it that is)
