currently conducting a small foray into the world of Facebook Competitions - it is a bit of a minefield really but I'll let you know how it works out
Intitial indications are good within an hour or two i have 20 entries and lots of new Facebook Page Likes -
you can keep an eye on things at http://www.facebook.com/blackhallframinggallery
Do any of you have experience of running competitions on Facebook? would it be something you would consider?
I plan to use the email addresses taken to send them carefully targeted correspondence showcasing the new artwork we receive. Which will shortly tie in with our website and it will all be good!
