It has been a little over two weeks since Mathchan became public. For those of you that celebrated eastern Christmas on January 7th: merry Christmas! Last week, we had Mathchan's dark theme added along with some general usability features. The site is certainly ready enough to be used to discuss mathematics considering LaTeX and preview are fully functional. In addition, certain boards have seen their own domain specific features implemented, namely:
\begin{itemize}
\item \href{/math/}{/math/ - Mathematics} now supports embedding commutative diagrams, 
\item \href{/chem/}{/chem/ - Chemistry} now supports embedding chemical figures,
\item \href{/ee/}{/ee/ - Electrical Engineering} now supports embeddnig circuits, through CircuiTikZ.
\end{itemize}
Each of these boards have gotten their own sticky detailing how to use those given features. We are now looking forward to enable embedding Feynman diagrams for \href{/phd/}{/phd/ - Physics}, data strutures for \href{/cs/}{/cs/ - Computer Science} and neural networks for \href{/ai/}{/ai/ - Articial Intelligence}. When they are done, they will get their own stickies as well. Afterwards, the next three boards will receive attention and so on. Every board is going to get its own sticky detailing the specific features Mathchan offers to the board to aid discussion of its topic.

Note that we already support embedding a lot of imagery through TikZ. For example, we can embed data structures such as binary trees through TikZ's trees library like the following: 

\documentclass{article} 
\usepackage{tikz}
\usetikzlibrary{trees}
\begin{document}
\begin{tikzpicture}[level distance=1cm,
  level 1/.style={sibling distance=2cm},
  level 2/.style={sibling distance=1cm},
  treenode/.style = {circle,draw=black,fill=white,align=center} 
  ]
  \node[treenode]  {A}
    child{node[treenode]  {B}
      child {node[treenode]  {C}}
      child {node[treenode]  {D}}
    }
    child {node[treenode]  {E}
    child {node[treenode]  {F}}
      child {node[treenode]  {G}}
    };
\end{tikzpicture}
\end{document}

Reminder that you can view the source code of \textbf{an}y post by pressing the \`</>\` button and copy paste it in your post to try it yourself by pressing the \texttt{Preview Post} checkbox to see how your post is going to come out without posting, or you can try posting in \href{/test/}{/test/ - Testing/Spamming}. Now if you check the source code of this post, you would see exactly how the structure above was embedded. The LaTeX code required to generate the structure is admittedly quite cumbersome and inconvenient. Wouldn't it be nice if there was a simple command such as \`\bstree{A(B(CD)E(FG))}\` that would generate the above structure? Yes - and there is going to be! Mathchan will have extremely simple commands that will generate structures such as arrays, list, trees, graphs and more - and that's not even the only thing planned for >>>/cs/, though we will reserve that for an announcment coming later. 

For now, the update is that there will unfortunately  be no updates until March 1st because Mathchan's development team will be busy with internal development that is essential but invisible to our users. After March 1st, rapid development of features that will directly benefit our end users will continue with new features detailed every Saturday. So for the four or five of you who are aware of this site's existence -- until next time!
