Eureka! I have positive proof that emails can work. You see WordPress had changed my beautiful sun background to a person strolling on a long shadowy path. (See the Mr. Wizard, Help! blogpost).
Some of my WordPress followers replied that they like the background; so I was resolved to learn to live with it even if I could not actually love it.
So… when I went to my blog today I didn’t even realize that WordPress had given me back my sun due to my “pleading” email request.
Thus I have proof that emails CAN work.
