ach - the competition is a good idea - I just posted a link onto my own webpage and on a couple of forums that I also use, basically saying "if you're interested in photography, click here, have a look, and if you want, then register" - the email link that Drew provided made it easy for me to do that, and without that link I wouldnt have bothered.
In fact it has taken me more time to write this post than the time spent on referrals!
I dont want to nor need to get paid for the referrals, but the nano would be a great toy for my nephew - the software would be a good toy for me! I'm happy either way. Hardly costs a moment of my time, and if anybody I referred goes on to buy membership for the site that's good for the site, good for Drew & his family, and good for me because the site keeps running

all in all a win-win situation.
