It's been rightly pointed out to me that it would be counter to my position that you own your content if we didn't allow for attribution to be removed.
This morning I was thinking of it from the perspective of a user that left, but wasn't determined to erase all history of interaction. It's my assumption that there are some.
I think the best way to do it would be a stepwise option. You can quit, your name gets a strike-through, or you can peace-out and your attribution is gone.
I'm not coding anything for the next couple of weeks as it is.
I should have given more thought to the matter before deciding anything. I'm sorry about that.
