Just to point out that the NAF isn't about running tournaments, it's about helping organisers run their own. The NAF only runs two tournaments itself, the yearly NAFC in the UK, and the 4-yearly World Cup (UK and Amsterdam so far).The NAF runs tournaments as well, but not often and they're sometimes remote.
As for tournaments being "not often and they're sometimes remote", the remote I can agree with you on (depending on where in the world you are of course), but often isn't a problem. Here in the UK alone there's 20+ tournaments a year.
[Edit] Just checked, and the UK alone has 31 tournaments planned for this year, and there may be others not on the list I checked.
