Hey Simon,

I am very sorry for my sloppy proofs.

I have gone back and tried to fix up my formatting in one of my proofs.

I thought

\[

\begin{eqnarray}

& A \\\\

& \iff \\\\

& B \\\\

& \iff \\\\

& C \\\\

& \iff \\\\

& D

\end{eqnarray}

\]

looks better on a mobile phone than

\[

\begin{align}

A & \iff B \\\\

& \iff C \\\\

& \iff D

\end{align}

\]

Since for wide expressions the latter tends to fly off the screen.

However, I will use the latter format because you are right, it is more conventional.
