Not sure if I'm asking an obvious question here, so apologies if I am!
I saw on the Winners thread that some people had won prizes from surveys they had completed on here. (Well done by the way!)
I regularly look around the site and if I see a survey I usually complete it. I did the Home Front one today, but it only asked me for my email address. I wasn't logged in and it didn't say I needed to be. I just wondered because on the winners thread, survey winners were identified by their username. My survey won't be linked to my username at all, just my email.
Do you need to be logged in to complete surveys? If so, should I enter again? Or will that invalidate me because I've done it twice?
Sorry if that's really confusing, but hopefully someone can work out what I mean!
