If you are in the game of registering people and collecting their emails, setup a facebook page and direct your traffic to it. No worries, people don’t have to be signed up at facebook to see your page OR TO ENTER THEIR DATA!
I discovered this by accident when I have been unable to get into FB this am. and popped one of my pages.
Then it dawned on me… some folks don’t need a microsite or blog unless they are restricting access pending a registration.
OK so maybe its not for everyone but a useful tool.
