I tried logging in initially via Facebook. It threw an error that I couldn't easily back out of. (you have to back button several times…)
It says you are in development mode and I don't have permissions.
Just thought you should know.
Thanks for letting us know. There are a number of website fixes/improvements that I want to make once we get the time (read: once the Siren's Call Kickstarter rewards are delivered). I'll make sure to add the Facebook login to the list.
