At the moment I'm planning a small FB competition. The plan is to encourage people to visit our websitesite to help them win the competition on FB.
To enter the competition they need to make something (to do with the website) and send us a picture of it via email. Receipt of the picture will get them an entry into the competition.
Whta prize could we give was a qustion I asked. I think it's going to be an Amazon voucher because that will cover people from a variety of countries, but not all.
Good luck with it.
