When I had SalesForce, there was a feature called something like Email Update.

Basically from within a contacts view, you sent that contact an invitation to view their basic contact information for updating.  They would get a “key” or password to access this one particular file.  From there they would enter their updated information.

Once they did that, I would get an email and then I could view their changes, approve them or change them myself.

I found this feature to be indispensable and really helped in the process of keeping things fresh and updated.

I would love if s360 could do something similar, where I could just send a request to a contact for updating, and they could do the work to update with their current info, upon my approval.
