It's possible that you either don't have Facebook or don't like sharing your FB details with Campfire. We understand!
We only use the FB registration to create some security for other users. If any random person could create an account on Campfire; we could have some very phony users snooping around.
So, in order to check if you also are a 'friendly' person we would like to ask you for another social account to contact us with (LinkedIn, Twitter etc). As soon as we verified this, we will create an account for you!
