The above are just test messages. Don't take the values of Omega_m there too seriously ;-). I wonder if http links get automatically converted, e.g. my article with Staszek and Gary independently showing that Om_m is close to 0.3 and that Omega_total is close to 1 (in the sense that the Universe is about as flat as a 1 radian radius surface area of the Earth: if the Earth is nearly flat, then yes, the Universe is nearly flat): http://de.arXiv.org/abs/astro-ph/0106135
