I have just bought it and it works really well. As a result I have 10 'invitations'. This means you get an email inviting you to try the software for 15 days (my decision to buy it took less than 2 mins). I don't know how difficult it is to get hold of these but if anyone would like one send me a private message including your email address and I will post your details. First come first served (and I'm saving one for my Fiance).
