I'm not sure what range or detail of comments you are after so I am just going to stick to a couple of minor bugbears on the NOTAM website.
First, it would be useful if you could use airfields as turning points for the narrow route briefing.
Second, I wish the military would put area names next to the co-ordinates when NOTAMing chunks of airspace as being active in military exercises.
Third, could royal flights not be NOTAMed rather than having to phone that telephone number?
Finally, it would be worth repeating the need for a graphic site with notams plotted on a map.
Other than that, it seems to work pretty well now and the NOTAM for Fort William that I got for a narrow route for a Norfolk flight on Sunday was a the first howler I'd seen for a while!
