Guest, See BelowNames are a 2-way affair. They're what people call you ... what they understand when they see you. People can address anyone as they like (they often seem to have done so to you far more rudely). My teenage children have all gone throught the "Don't call me ..." stage and grown out of it.
Please don't get all excited and upset, it isn't necessary. If you want us to call you "All", why don't you just use "All" in your From: line? Doesn't seem all that hard to me. Or oppressive.
I seldom do what I'm told (but then neither do you).
Cheers!
