Thanks. I don't know either. With all the different configurations, interdependencies, and failures to adhere to standards, I'm generally surprised anything runs at all. It did show fine at first (5-10 seconds), then converted into pseudo-Greek.
I did click on your Post 156 (this thread) last night--nothing there, it just expanded my screen. But your separately posted quadratic test equation did work well for me.

Worked for me too on my phone. Opened in what looked like the original text and quickly converted to what I assume was the intended equation.

Check above and see the PI symbol for the equations.
That was quick turnaround! Thank you so much! We've been needing that for a while now.

Everything from That thread except a Certain Member's Posts reads in English for me.

Is there still a way to do subscripts & superscripts?

I tried both BB and HTML and couldn't get it to work. That does not mean it doesn't.

Could we get a "New Post" button at bottom right of each thread page?
To avoid having to scroll back up and reaching across to top. (on iPad)

At the bottom right of the page is a UP arrow. That will take you to the top of the forum and the right side New posts will show you the New Posts you have not seen.

Or you can click New Posts at the top bar to get new posts. (Image from ipad).

How often would these be used?

More often than you might expect - if they are available. LaTex is nice for complex formula but when we just want "something ^exponent" or a coefficient with an identifying subscript they are quick and increase the clarity of the post considerably.

I do use the up UP arrow to scroll faster. But it still takes two clicks to get to New Posts each time.
I used the "new post at top, reverse order option" with the old V bulletin.

Fairly often. We use units and variables like ft^2, ft/sec^2, C-sub-l, C-sub-m, etc.

The new latex feature is awesome (!) although if you use it to try to use C_m in the middle of a sentence, it doesn't show up inline. Example:

That airfoil's $$C_m/\alpha$$ curve doesn't meet my needs.
If latex could be used inline with regular text then there would be no need for superscripts or subscripts. Also see this thread for more on latex and links to symbols and such.

You can do some things with font characters:

L = ½ρV²ClS

No subscript letters, though

Did you do that by copy/pasting from the character map?

Yes, though if you know the character code you can do it with the alt key, e.g. alt-248 is the degree symbol °, etc.

Thank you.

Forum seems to work fine w/ Firefox ESR in linux. Haven't yet tried writing any formulae, though.

Dana, how exactly did you make the 2 superscript on the dynamic pressure in your lift equation?

Couldn't get the degree symbol to work so I will use improvised notation, for example, degF.

That time, I cut and pasted from the Windows character map, but you can use the keyboard too:

° degree symbol ALT-248 or ALT-0176
± plus/minus ALT-241 or ALT-0177
² superscript 2 ALT-0178
³ superscript 3 ALT-0179
Greek letters π, ρ, σ, etc., character map only.

I’m not sure how to do it on a phone since there’s no character map or alt-key (the degree symbol is on the 2ndpage of the android keyboard, though).

One hint, for desktop users: The numbers have to be entered on the NUMERIC KEYPAD, not the row of numbers above the alpha characters.
