richard, for your first 2 points, unfortunately this has nothing to do with the nsw club/exec team.
it is/should be controlled by the moderation team, put in place by the sau forum creators/runners should be keeping tabs on that.
how much would it cost to buy the box, get it shipped, pay taxes and duties, and the fabricate to make it fit?
possibly around the same price as buying a dog box locally?
or, buying a dog gear set and getting a box built?
some other options.
