Two points Greg. The less you have to do to pinpoint somebody’s dive site the better. If somebody wants to go to their favorite spot, have them name it or link it to the scuba earth/dive site page.
Second point. Although I suspect overall most divers are of above average intelligence, this is not true in all circumstances. Thus, the simpler it is the better (Somebody will still make a fuss over the simplest instructions.) The dive site page is already in place with a link to that you save yourself much more work. (Unless you are into self immolation then go for it I’ll bring the hot-dogs and marshmallows) ;-) Ok, I am cynical and twisted.
