I have Gmail and sometimes i get copies of my own emails from various groups and sometimes I don't. But per the instructions, at least with my display, I can select Account in the manner suggested but then it differs.
On the resulting page Preferences in not on a left side menu and there is no drop down menu on the left.[see attached image] Preferences is in a section on the right with a heading and a gear wheel. The heading is active. When I click on it I am taken to a page called Preferences. "Set up your account so it works for you," is at the top of the page. It's not active. [see image attached] The words "always want copies" do not appear on the page. (I don't see them and I did a word search.) There is no checkbox. Peter if you're a bit thick you have company!
I am attaching two screen caps showing what I see.
