[MM3-users] Social signup?

Hi everyone,

Is there a way to enable social signup (vs just login for existing users)?

I've just implemented social login on my mailman lists, but realised it seems to be only login, and not signup...or at least I couldn't fine specific info to enable social signup.

Is social signup something anyone has implemented (and if so how). If not, I suspect there might be a good reason (e.g. privacy, security, etc) but I'd love to hear it :-)
