Dear All: I write this with my tail between my legs, because I am positive that, if I looked around in the archives etcetera, the information would be there. So, with apologies (no laziness here, just inordinate haste), could anyone drop me a URL or two that might answer the needs explained below? No need for anyone to waste time writing: just toss me the URL! :-) What I need =========== The IUMJ abstracts are in MathML. Sometimes we luck out and the rendition is just fine. Sometimes (for example, when using something as simple as $\sqrt{2}$), the browsers ability to read perfect MathML is atrocious. Solution: use ConTeXt to convert MathML to perfect PDF's. And the best URL to learn and do just that is... Many thanks, hope to contribute something soon, best, elena
