EESDL,
Have you tried the new url?

The (horrible) functionality still seems to be the same for narrow route briefings. However, things seem to be a little bit more sensible because you can now get an 'area briefing', centred on a particular position.
Otherwise, I always found NotamPlot or NotamPro a much more user-friendly way of publishing NOTAMS.
