Yea its not too difficult. Wait for the pods to start to split so you know the seed is ripe. Depending on how much you want to save and plant, you can rub the "silk" off by hand or I have seen them throw it in a cement mixer and run it for a bit in some sand to pull the "silk" off. I would guess the seed probably needs to be cold stratified prior to planting. Or plant and let Mother Nature stratify it for you.
