lettersnewlfmsectioning
I want to use sectioning in letters (section, subsection, etc), but here I read that basically all of these sectioning commands do not apply to letters. What is the proper way to create sections in letters?
Using: documentclass[stdletter]{newlfm}
Perhaps not the best option, but you can use the dateno class option
\documentclass[12pt,stdletter,sigleft,dateno]{newlfm}
to avoid automatically typesetting the date and then add \today in \addfrom, to inherit its alignment
\addrfrom{%
\today\\
Predrag Puno\v{s}evac\\
Science Laboratory\\
Some University\\
Urbana, IL 61801
}
Here's a complete example using portions of your example code (I suppresses all commands using the image since I don't have the actual image file):
\documentclass[12pt,stdletter,sigleft,dateno]{newlfm}
\usepackage{charter}
\widowpenalty=1000
\clubpenalty=1000
\newlfmP{headermarginskip=20pt}
\newlfmP{sigsize=50pt}
\newlfmP{dateskipafter=20pt}
\newlfmP{addrfromphone}
\newlfmP{addrfromemail}
\PhrPhone{Phone}
\PhrEmail{Email}
\namefrom{Predrag Puno\v{s}evac}
\addrfrom{%
\today\\
Predrag Puno\v{s}evac\\
Science Laboratory\\
Some University\\
Urbana, IL 61801
}
\phonefrom{000-000-0000}
\emailfrom{xxx@hotmail.edu}
\addrto{%

One option using the titlesec package to define two new units; the alphalph package was used to provide the counter with double alphabetic characters.
The two new units are \myunit and \mysubunit, with levels 6 and 7, respectively; I also added support for bookmarks for the new units. Of course, change the settings for the headings and for eventual ToC entries according to your needs:
\documentclass{article}
\usepackage{alphalph}
\usepackage{titlesec}
\usepackage{hyperref}
% declaration of the class for the new units
\titleclass{\myunit}{straight}[\subparagraph]
\titleclass{\mysubunit}{straight}[\myunit]
% counters for the new units
\newcounter{myunit}
\newcounter{mysubunit}
% all units numbered and in ToC
\setcounter{secnumdepth}{7}
\setcounter{tocdepth}{7}
% modification of heading format for section, subsection, subsubsection
% to add the period after the counter
\titleformat{\section}
{\normalfont\Large\bfseries}
{\thesection.}
{1em}
{}
\titleformat{\subsection}
{\normalfont\large\bfseries}
{\thesubsection.}
{1em}
{}
\titleformat{\subsubsection}
{\normalfont\normalsize\bfseries}
{\thesubsubsection.}
{1em}
{}
% heading format for the new units
\titleformat{\myunit}[runin]
{\normalsize\bfseries}
{\themyunit}
{1em}
{}
\titleformat{\mysubunit}[runin]
{\normalsize\bfseries}
{\themysubunit}
{1em}
{}
% spacing for the headings of subparagraph and the new units
\titlespacing*{\subparagraph}
{0pt}{3.25ex plus 1ex minus .2ex}{1em}
\titlespacing*{\myunit}
{0pt}{3.25ex plus 1ex minus .2ex}{1em}
\titlespacing*{\mysubunit}
{0pt}{3.25ex plus 1ex minus .2ex}{1em}
% redefinitions for the counter representation for all units
\renewcommand\thesection{\Alph{section}}
\renewcommand\thesubsection{\Roman{subsection}}
\renewcommand\thesubsubsection{\arabic{subsubsection}}
\renewcommand\theparagraph{\alph{paragraph})}
\renewcommand\thesubparagraph{\alphalph{\value{subparagraph}})}
\renewcommand\themyunit{(\arabic{myunit})}
\renewcommand\themysubunit{(\alph{subsubsection})}
\makeatletter
% bookmark support for new units
\def\toclevel@myunit{6}

% ToC entries format
\renewcommand*\l@subsection{\@dottedtocline{2}{1.5em}{1.5em}}

Here's one possible solution, using the kernel command
\@startsection(you chan find a description of this command in Where can I find help files or documentation for commands like \@startsection for LaTeX?) to redefine the\sectioncommand (thenewlfmclass offers a very basic\sectioncommand) and define the\subsectioncommand to behave as those fromarticle.cls. Basically, all you have to do is to define the counters and use\@startsectionwith appropriate settings. A simple example:The previous solution doen't make provissions for a ToC, but this is also really simple: all one has to do is to define
\tableofcontentsusing\@starttocand define\l@section,\l@subsectionto typeset the corresponding entries.
