I find that <br>
this class automatically inserts the state to the right following the <br>
senders' mame and addrress.<br>
<br>
The date is displayed default with the format July 11, 2022.<br>
<br>
I prefer the date be closer to the ISO standard. I want it to be like <br>
the output of<br>
<br>
\def\mydate{\leavevmode\hbox{\the\year.\twodigits\month.\twodigits\day}}<br>
\def\twodigits#1{\ifnum#1<10 0\fi\the#1}<br>
<br>
which is 2022.07.11<br>
<br>
I tried placing \newcommand*\today{\number\year.\number\month.\number\day}<br>
into the preamble, but lualatex complains that \today haa already <br>
been defined.<br>
