Mike,
I suppose that those of us who haven't taken such a degree of interest in the workings of AIS might be unaware of what it can do (I am and I agree it can do all we need, viz. my recent trip to Germany mentioned in another post).
For me though, the question by IO540-C4D5D highlights the need for two things:
1) improved user friendliness of the site making the availability of these features more apparent and easier to intuitively understand how to use (of course hell might freeze over first, notwithstanding the fixes already achieved!); and moreover
2) the need for an educational / tutorial pamphlet showing how to use the site.
I have suggested on the feedback form that comes with the excellent "Get Met" booklet that they include a "Get NOTAM" section for this purpose.
Best,
Andy
