Need capability to use subscripts and superscripts

Thats a good idea, hope Biggie makes the change. I still have to learn how to use these features for their full capabilities.

I'm aware of the problem that Mr. Beychok mentioned. For an engineering forum, ability to have subscripts & superscripts. However there is a big problem with HTML or VBScript enabling - It makes the site vulnerable to attacks.

I've not yet toyed with the BB code. Will try it out and update soon.

Oh yea.. thats a good idea. Things like integral and differential signs, Fourier transform stuff, etc. One alternative is to use that Microsoft Equation object in Word and insert as a picture. But that involves so many steps.

You might want to look at these forums:

(1) Eng-Tips Forums at <a href="https://www.eng-tips.com/threadminder.cfm?pid=798" target="_blank" rel="nofollow noopener noreferrer">Chemical process engineering Forum - Eng-Tips</a>, scroll to bottom of page and click on "Process TGML" and see their extensive list of tags.

(2) Chemical-Engineering-Forum at #-Link-Snipped-#and see their [sup] and [sub] tags.

(3) CR4 Forum at [FONT=Helvetica, Arial, sans-serif]#-Link-Snipped-#[/FONT] and see their
X2 and X² tags.

...anyone here doubts why the Administrator calls himself 'Good Administrator' 😉

A warm Welcome to everyone[sup]2[/sup] ! 😁

How are you?

I just drank a glass full of H[sub]2[/sub]SO[sub]4[/sub] & then ran at a speed of 1.5x10[sup]2[/sup] m/sec!

Have fun!

Forgot to explain how to add superscripts & subscripts to your text.

For subscripts, use the "sub" tag in square brackets, without the quotes.
For superscripts, user the "sup" tag in square brackets, without the quotes.

Yay![sup]2[sup]2[sup]2[/sup][/sup][/sup] Can we add some maths symbols too?

Admin:

Thanks very much for your very prompt provision for using subscripts and superscripts!!

May I suggest, that for the great many users of this forum who may never read this thread, you include an explanation of how to use subscripts and superscripts in the message editing/posting box?

Regards, Milt Beychok

Right now, we cannot use mathematical symbols in posts. But we'll see if we can develop such utility.

For subscripts, use following tags around the text-
"sub" text "/sub" ( Replace the quotes with square brackets [ ] )
For superscripts, use following tags around the text-
"sup" text "/sup" ( Replace the quotes with square brackets [ ] )

So, to write H[sub]2[/sub]SO[sub]4[/sub] , I will type -

H "sub"2"/sub" SO "sub"4"/sub" ( Of course, replace the quotes with square brackets [ ] )

Hey Big K! I cam across this thread over at the Physics Forum. They use LaTex to display the maths symbols. Is it possible to implement this without compromising the site's security?

It'll be awesome if we could use it! 😀

Awesome response time Biggie 😀

You guys are just great 😁 . Give me some time to understand the LaTex system. I'm bit too busy traveling around.

kidakakaAwesome response time Biggie 😀

<- that's what I am! 😁 Thanks a ton!

Cool, thanks Big K! If you need some extra help finding out how to implement, i'll do some extra research if you want 😉

Going on a roll with looking through vb addons, I found this one that can add LaTex symbols.. but as images, however.

Its for vb version 3.5.. I wonder if it is still compatible, biggie?

Yep, I guess there is compatibility issue.

Once upon a time at a grocery store.[sup].[sup].[sup].[sup].[sup].[/sup][/sup][/sup][/sup][/sup]

Shop Keeper: blah[sub]h[sub]h[sub]h[sub]h[sub]h[/sub][/sub][/sub][/sub][/sub] blah[sup]h[sup]h[sup]h[sup]h[sup]h[/sup][/sup][/sup][/sup][/sup]

Nice creativity, xHx. The problem is that members don't use the subscript & superscript facility.

Therefore, any add-on, won't be added unless the 'need' is felt. Otherwise, its difficult to battle with the compatibility issue that's common with all the plugins.

I participate in half a dozen engineering forums. Posting technical engineering material very, very often requires the capability to use subscripts and superscripts in mathematical equations, chemical reactions, etc. Most of the forums that I participate in have that capability in their message editors and almost all of them use BB or vB code and Wysiwyg editors ... so I know that the capability to use subscripts and superscripts is available.
