Conventional means its the natural ring surface of the stave.  Decrowned means it was from small diameter tree stave with a lot of curcature, so you flatten it out.  Bias ring orientation means if you look at what will be the back, the edges of rings are vertical, parralel to each other while at the end of the piece they area at a 45 degree angle.  Edge ring is like bias but at the end, the edges of the rings are perpendicular to the back and belly

I think there are better explanations and diagrams in volume one if I remember correctly.  Hard to say since I am at work and don't have them with me though.

Hunterman, you will have a lot of "ah-ha" moments in this hobby. I know I have, and will continue to have. Relax and it will come to you as it comes to you. This site is the best single resource you can possible find, too.

All those terms just refer to the way the growth rings are oriented in the wood. A conventional stave is split from a log, unsawed, and the back follows one growth ring. An uncrowned stave has the crown (roundness) flattened off the back, sometimes done to small diameter staves to remove excess crown or to make it easier to back a stave with something like bamboo or a slat of hickory. Plain-sawn lumber has the rings oriented like they would be in a split stave, edge-grained boards are sawed at a 90 degree angle to the rings, and bias-sawn boards have the rings running at a diagonal angle.

Progress might have been all right once but it's gone on for far too long.

Wudaya mean clear as mud.  I thought my explanation was pretty concise.  The pics are a great touch though.
