@Jack_Spade: This is all going to end in tears, I know it. BTW, unless you've bought Prime Datahaven Access out of Data Trails, you probably won't find too much on JP, since I don't think you can actually ask questions of the other JackPointers without it. If you have, a couple of Goodnight's contacts DID buy it, and I can post messages from them if you start asking around. Just a search won't give you a whole hell of a lot, though.
