Login by email adress in JFBconnect

That's not a standard Joomla ability, so we don't support it out of the box. Are you using another component or feature to allow logging in with email's right now? That may help us come up with a solution that will work for you.

That's not something we support, unfortunately. For standard Joomla logins, we use Joomla's User Manager component which only let's users login through their username. I looked quickly at the JED, and didn't find a plugin which lets you login using your email, but you may have better luck.

Hope this helps, though I know it's not what you're looking for. That functionality is simply outside of what JFBConnect is meant to do.
