##### LaTeX implemented on forums

Hi everyone,
I've implemented LaTeX on these forums. Essentially, LaTeX is a markup language allowing you to format maths equations so they're all nice and stuff, and will help anyone who's posting equations in their post. To use it, simply use the $$BBCode in your posts. Here's some examples: Code: [tex]\sqrt{x^2+y^2}$$
Output: $\sqrt{x^2+y^2}$

Code: $$\frac{-b\pm\sqrt{b^2-4ac}}{2a}$$
Output: $\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Code: $$\int_{-10}^{10} 2x^2 dx$$
Output: $\int_{-10}^{10} 2x^2 dx$

Hope this is helpful for you guys. I'm still looking for some good LaTeX tutorials, there's one at http://www-h.eng.cam.ac.uk/help/tpl/textprocessing/latex_maths+pix/latex_maths+pix.html which seems quite good

To enforce spaces, use \mbox{}

For example:

Code: [Select]
\mbox{Hello world}
$\mbox{Hello world}$

Code: [Select]
Hello world
$Hello world$

Wow, I just thought of a good use of LaTeX to protect from spam bots.

Instead of the not so pleasant: "username AT domain DOT com", you can avoid spambots and still have your emails look proper to humans:

Code: [Select]
$$\mbox{[email protected]}$$$\mbox{username@domain.com}$

Since LaTeX is printed out as a picture file, spambots cant read it! I've now modified my tutoring ad to use this innovation

They still can, as the image's location contains the email address: http://stuff.daniel15.com/cgi-bin/mathtex.cgi?\mbox{[email protected]}

Some may also have optical-character-recognition spiders, that can simply read the text in the image.

Hmm... I'll try to obfuscate it somehow then. I'll try to make my email pretty easy to read for a human, and I'll take my chances that there's no OCR spiders (pls)

EDIT:
Code: [Select]
$$\mbox{coblin}@\mbox{gmail}.\mbox{com}$$$\mbox{coblin}@\mbox{gmail}.\mbox{com}$

Here's my obfuscation attempt.
