XF 1.3 Make e-mail not unique?

I want to make 3 sites share the same database using the multisite addon. Issue I am having is using facebook connect.. each site as a unique AppID to login to the correct domain for that site. So if you register for the first site. Registering for a second site you receive the error - Email addresses must be unique. The specified email address is already in use.

How can I remove the e-mail being unique requirement?

You would need to ask in the multisite add-on thread.

XenForo requires all email addresses to be unique.
