It should also work if there is no full-moon, after all, what do you have your computer for?

This will only work for restricted regions, for (a) to be able to `see' you have to have the same light conditions as the originating MELSD site (i.e, night). (b) due to the diffusion angle of our nowadays lasers the distribution of news or any network items will be limited to certain regions only. > > jon > > > -- > Jon Wells @ O'Dowd Research P/L.
