WOW! Cool!!
Tripler
Thank you!
Yeah I saw @Chronos post those elsewhere so I tried it here. Pretty cool!
Sorry for the delayed reply @Tripler .
It’s all good. Is this what they mean when they say “using Latex” or is this something else?
Tripler
I can look up how-to guides and post 'em here.
Actually I’m not sure.
Basically, yes.
Imagine that you are working on some sort of scientific paper, but this is back in the early 1980s and you are typing your paper into a text-based terminal. You need some way to write mathematical formulas, so someone takes a typesetting markup language called Tex and adds math stuff to it. They name it LaTeX. This becomes very popular in academia because how else are you going to write math formulas on a computer terminal?
So years later, lots of folks use LaTex but there’s no easy way to put it on a web page. That’s when some folks create a JavaScript library called MathJax, which supports LaTeX along with some other similar things (MathML and ASCIIMath).
And that’s what we use here. We have the MathJax plugin for Discourse installed.
Thank you!! In my über-nerd way, I kind of look forward to goofing around with this feature!

But not at work. That’s for serious math. 
The superscript and subscript tags, sup and sub, work also:
33 ft/sec<sup>2</sup>
gives you
33 ft/sec2

Just nitpicking: TeX was designed by Knuth from the start to typeset math. (I used plain TeX to typeset my thesis in 1985.) It also had the ability to define macros and do some programming. Lamport then designed a set of macros to improve on a number of things, particularly better separating the presentation (what things look like) and content (how things are organized and what they mean conceptualy) aspects. That set of macros became LaTeX. Most of what MathJax implements was already present in the original TeX. But LaTeX became so popular that most users now probably aren’t aware of the underlying plain TeX anymore.
I wasn’t aware of that. I thought TeX was just a general typesetter. Thanks for the correction!
Test to see if images can be used instead of text in a poll.
Testing a canned reply use code:
\text{}{\color{blue}\mathbf{GIANTS}}
Hmmm, perhaps this?

Image B —
Not sure what you did - just a series of labeled choices followed by their images. Okay, but not ideal. Would be better to have the tick boxes and the images, one next to each box.

And there we have it!!
test of map display
I see Hayward, Wisconsin, and it zooms and scrolls just fine. Neat! ETA: Also street view works fine.
Yes it looks really good.
I was just seeing if the map would show up in the thread. No special reason for choosing that town. But the map doesn’t show up in the preview, so I wasn’t sure.
