For new accounts moving forward, depending on what method you use to log in (email, facebook, twitter, google), if the email address for login method matches an existing email account, the logins will be unified and both be associated with the same user (you may receive a confirmation link to confirm that you own the email).
This avoids the scenario that happens sometimes when attendees:
- Join your event with a social login (example: Twitter)
- Come back to your event later and login with a different method (example: Facebook)
- End up with two accounts and in some cases register twice.
Now, when the email addresses match the above scenario will result in two different logins that both access the same user account, which results in much less confusion for attendees.
