When typing in the question wording, is there a way to do any formatting at all? It would be helpful to be able to add emphasis (boldface, italics, and/or underline), superscripts and subscripts, and mathematical symbols (such as sigma for summation). So far the only way I've found is to create an image (by copying a textbox into paint and saving it as a .bmp or .jpg file), but then it's sometimes fiddly to position the image neatly.
