Rick you always make me laugh.
I had to get the Gardening Ideas feature implemented - it was an important priority for me. But now that's out of the way, the very next thing for me to roll up my sleeves on is the trading feature. I promise you, you're going to like it. It will be useful for much, much more than just trading.
It will definitely be done in phases, and I plan to release early and often, building an initial simple system and launching that, and then adding on to it all the features I have planned. That was the method we used in developing our database feature and I think it worked very well.
