There seems to be a bit of a "conflict" with one of the code tags
Many programming languages use square brackets to provide a way
to access a single element of an array.
It is very common to use this within a "FOR" loop, and the most
common variable used in these loops is simply the letter "I".
So there is lots of code out there that looks like:
MyArray[ i ]
Without the extra spaces I added here, the board interprets this as
an "Italic" tag.
Maybe it would be better to require [ italic ] ... [ /italic ]
for italics, instead of just [ i ] ... [ /i ]
