/*IDEAS

//for Chrome workarounds (which I may never try)

For Chrome, use an iframe, and set iframe.contentWindow.document.body.innerHTML=cf.innerHTML
and bring over the CSS to style it. Have it take up the minimal amount of space at the start,
but, if someone clicks inside of it, then it resizes itself to take up one entire screen.

Or, a lesser solution, when you click inside the comment box, just resize it to be the screen
height, minus the space needed for the post button. Make the post button a fixed div that stays
at the bottom of the page as long as any element in the form is active.

//other
maybe add autosize button that will remove the user-defined size (and shrink or
grow the textarea on Chrome).

add another post button in chrome--one on top the textbox

see if there's a way to detect when the comment box is active, and hide the rightmost
column, allowing for a larger comment box.

Add a mazimize comments button, both at the top and above the comment box. It would
hide the other two columns and set the width of the middle column to auto.
