Actually would br much better to return a variable - google, facebook, github etc, you can then use it as a css class to implement this everywhere in forun (profile, postbit etc).

That exactly is the plan.

Well, we need to discuss on this.
Few people indicated this as a privacy exposure.
Do you really need to know how he has registered? On permanent basis? When we are ensuring the security in entrance ...

If at all admins wanna know, there can be a log, prunable.

Thoughts?

I think this is a security (privacy) issue. So maybe we can just add some log in ACP.
