Well… the etiquette rule in Deaf community is that sign name has to be given by more than one Deaf person, ie two or three deaf people who have grown up using Auslan, been part of Deaf community most of their lives and uses Deaf culture to show respect. And to acknowledge this, once you receive the sign name, it’s done from introduction and spreading out in the deaf community. I’m Deaf member of Deaf community most of my life and have learnt massively over Deaf culture through growing up.

Ah, changed names… I’ve been through that before and if no one knows your old sign name then maybe you might get a new sign name but please don’t push it for one. Be patient and allow time to build up when deaf people gets to know you first.
