Is it true we must never delete a page or change the title?
I just read this comment by another member in the Level 1 Classroom:
I found out the hard way it is best to save as a draft until you are positive that is what you want to name them. I should have waited till I really knew what I wanted to name my pages. Well I deleted one because I wanted to change it to something else and I got a 404 error from google, and the page don't go away. And google frowns upon this. I found out through help of WA community to never never delete or change name of page or post. So I always try to pass this on to others so they don't make the mistake I did.
My question: Is that true? I never knew that and I think I have done it before! :0
