On the basis of the memoir class and Maggi Memoir Thesis I tried to begin formatting my thesis. However the title page is not centered but I would like it to.
I would like to remove the right box only for the title page so that it is not only centered inside the textarea but for the whole sheet of paper.




\input{Intro.tex}as we do not have it and it is irrelevant to this question. (2) Please explain what is wrong here. Parts of this is centered others are not. What exactly do you want? BTW: I tend to code the entire title page by hand inside thetitlingpageenv instead of using\maketitle. – daleif Nov 10 '16 at 10:35textarea(what happens with\begin{center}or\centering), but not regarding the sheet of paper. Cf. e.g. the canons of page construction (where page border are shown in black, and text area borders in red). You can check this by showing borders of the text area using\usepackage{showframe}... – ebosi Nov 10 '16 at 10:44typeareapackage therefor). – ebosi Nov 10 '16 at 11:17\calccenteringin the memoir manual, I tend to use it with a doubleadjustwithinsidetitlingpage, the outer to center with respect to the paper, the inner to change the margins of the titlepage (often to make it wider than the text with of the doc). – daleif Nov 10 '16 at 11:18
