I'm not sure if I like the new Rafflecopter. It confuses me. If you win a giveaway, since it doesn't ask for your e-mail address, how do you know if you won? Will it send you a message on Facebook, or will you have to check the blog you entered the giveaway on? I just entered 175 giveaways for a giveaway hop, and am not going to feel like checking every single blog to find out if I won or not.
I have entered several with the new one as well as am finally hosting my one with the new format. I don't ever sign in with facebook (I choose the name and email option), but I believe that it will pull the email address from your facebook account. So you should be checking whatever email address you use for facebook.
I don't remember the password to my email from facebook. lol
