I added and removed from Amethyst so many times. Petnames for me must be private. Most people assume it to be private: like calling a brother "Replaceable Parts", etc. If you use the public version make sure to tell people that it is public.  

 Agreed on the privacy aspects.

I have a contact list on my phone and for emails and neither are global access. 

 Does this mean petnames are coming to Amethyst? 

 With something like the Relationship Status, yes. It's a must. 

We just need to confirm if that is how we want to do it.
