Every flying organisation I've been into (though admittedly a small sample uk side), have an 'office copy' of the days weather and notams printed out and left in a public place where one can pick up and read. (though I do seem to recall UK notams being in a rather unhelpful lat-long notation, rather than related to significant points on the map)
Not the GPS arguament again? As you already pointed out they're not reading the notams, I rather doubt navigational accuracy is the issue in this case. Besides, if the UK GA populace are so computer illiterate they can't get notams, they've got **** all chance of figuring out how to drive the average aircraft GPS.
Personally I'd prescribe some serious slappings until people start taking their responsibilities a bit more seriously, rather than making excuses for them, but hey, that's a bit old fashioned in this day and age..
