I don't know if this has been posted yet or how long it will last so I might as well share it anyway. Link Assistant are giving away SEO PowerSuite Enterprise free with legit licence keys (on the link, I won't post them here to be on the safe side). I don't know how long they keys will last, or even how good the tool is, but you can't complain at anything for free I suppose. http://www.link-assistant.com/halloween2011/contest.html
