Went out of his way? Once a signature is created it is easier to post WITH it than without. I actually go "out of my way" to uncheck the signature block on most of my posts, because I don't want my signature to interfere with what I'm posting. (I'd delete the signature completely but there are posts where I want it there.)
The bolded part is the point I was making, The smart phone app for DBSTalk app automatically adds it so.... You have to go out of your way to create a regular signature (which I have one) and it's a default on the app.
Something tells me you knew that though.
