The other prblem with WWW's suggestion would mean that people couldnt practise using D&D post qualification - I seem to rememeber some material coming from D and D a while back asking for people to call them for their own training. I'm sure they are quite capable of telling people to bog off if they are busy with real emergencies.
I do agree though that if you are lost you shouldn't use a training fix; but human nature is what it is.
