For most it was the fact it was illegal to use AM here that made it fun I sold my set up as soon as FM licences arrived.
Hamsphere is legal without a licence and for me the big draw Is you can speak to people all over the world using a PC/Laptop or mobile phone, if you don't want to get into conversations you can keep it short and can then swap QSL cards so you can keep track of where you have made contact you have your own page in the website where you can view all you stats edit QSL cards and lots more, I am still using the 30 day trial but I will pay the £25 annual subscription when it ends.
An example of a QSL card below.
