<TEXTAREA COLS="12" ROWS="2" NAME="Not a good idea" WRAP=PHYSICAL>Bad idea. Call it a hunch, but I suspect that many people would quickly get irritated by that. We are having enough trouble just getting people to use <CODE> tags. Just imagine the fiasco with all sorts of randomly sized textareas showing up (COLS="300" anyone?)
Update: For those confused by the replies below, this node used to be in a tiny, tiny textarea (2 rows and 12 columns). The HTML is still there, but apparently the Everything engine now strips it out.
