Installed app and plugin - looks good - everything as expected.
When using it the first time, I get a "This email is already registered."
I use the same email address for FB and my website and have some other users that probably do the same thing - ie re-use their email addresses.
Registration is selected in the plugin. If it is colliding with an existing email address, what will happen the second time it is used (after registering on the first use)?
