I can't find any resource on the use or meaning of the above buttons when sending a question....
when do you use quotes and why
when do you use 'code' and why
when do you use 'Mcode' and why, how is it different from 'code'
when do you use 'Source' and why
how do you send a screen shot -- I can't get image to work for me
when using 'Copy As' in Mathematica, when do you use 'Plain Text' vs 'Input Text' vs LaTex vs MathML vs Cell Expression vs Notebook Expression?? all producted gobbledygook for me. I tried using Help, but it only throws back at you the same word you are trying to understand and is of little value.
