Indidjinus: Dedicated to the sharing of the history, craft and culture of the didgeredo. (something like that)
I’m no copy editor, but from what I know even simpler is better and I’m thinking
InDidjInUs: Dedicated to sharing the music, history, craft, and culture of the didjeridu.
I’m using with the J spelling because it’s how it’s spelled in InDidjInUs. The order of music, history, craft and culture is arbitrary but I can see purposefully arranging it either in order of priority, to make it flow better, or just to make it easier to remember.
