Wow, a survey!
Well, sort of. I got an email from one of the sites. They have already given me 40 points for signing up with them (15 points = £1.00) and sent me a personal survey worth 20 points that took about 5 minutes to complete. It was a survey about me and my interest. It will allow them to see what surveys I am most suited to. So, I now have 60 points which equals about £4.00, not bad I suppose.
I really should have timed how long it took to take the surveys. That would have given me a better idea of how worth while these surveys are in terms of payment-per-hour.
