Howdy,
Roy Vail gives an interesting lecture and has lots of experiance growing stags. In fact has by far the best book on the subject. You can get it from Amazon I think. Or you can attend and he may have some for sale. No color photos but lots of B&W in the back.
Several members of the Texas Gulf Coast Fern Society grown many different kinds of stags. I have gives a couple of presentations on dividing and remounting large clumps of stags. In general watering can be a problem. The best technique I've found is... as soon as the moss is completely dry, submerge the board in a large bucket of water untill it just stops bubling (about 5 to 10 seconds) then hang it back on the hook. If it's too hard to remove then, hose it down once for a few seconds, then go back to it a time or two again and hose it down again. Good air circulation is important, also give it as much light as you can without burning the fronds.
