I am a Facebook resister and had no problem signing up yesterday using my email address only. The site is a little slow in registering you and I had better luck with clicking on the Vote for this Idea button which launched a pop up window for registration. One thing to be careful of is that for some reason, the original registration window's default is "yes, I have a Password" so you have to change that to "I'm New Here" to get prompted to continue registering. Try again?
