Will the <math> tag be available as in wikipedia? This may also help get rid of (some of) the "diversity" in writing e.g. sums that Doug McNeil complained about, though we'll still see <math>\sum_{k=1}^\infty f(k)</math>, <math>\sum_{k\ge1} f(k)</math> and <math>\sum_{k\in\N} f(k)</math>, but at least these correspond to "standard diversity".
