Changing Adywan to AD1 will make little if any noticeable difference (Sci-Fi to SyFy).

See-Threepio and C3PO are still the same characters and besides you are still the eye of the tornado.

You are the originator of the enterprise.

It's your work that got other people to volunteer to help and maybe get a bit overwrought when they don't get to play on your team. You are still doing the bulk of that work.

Adywan isn't your name anyway but it is a recognisable symbol for what you are trying to do. If someone finds an old article about Revisited, Adywan is the search term they will use to find out more.

If you start adjusting it to AD1 some people may not being able to find what you have done and if you keep your current screen name in articles to keep the search option open what's the point of the name change?

Personally I'd keep the name the way it is.

Maybe add Associates or something like it to the 'brand' to highlight that it isn't just you.

Besides you shouldn't propagate the illusion of professionalism.

You are an amateur in the true sense of the word.

You do what you do out of love of the craft and not for money.

You should wear that badge with pride especially in these greedy times.

Maybe United Amateurs would work as a satire of that other UA.
