Hi,
How can I avoid duplicated User accounts?
For example: A user has a normal registration, with membership pro activation, (or any manually activated membership) After a while, he wants to enter through Google+... and this will create a NEW account for the same person, with another e-mail. After that, he writes to me his because his access rights are truncated... and I have a mess to resolve: canceling second and third accounts, transferring his comments to the right original identity...
I suppose You have an elegant way to resolve this problem.
Thank you a lot!
