When the time is right. Not my first rodeo. The biggest issue is that it adds a lot of stress on those who wish to be creative in private first, then reveal. FWIW, I published a book in the open, I was anonymous as I was writing the book (historical fiction), the amount of grief I received behind the scenes during the process, I would not have been able to handle if I had not been anonymous.

All I am saying is to respect someone's privacy if they wish to develop in private first and then decide to publish in the open.
