Is this Sam's talk? He did a very similar talk at Dorkbot about this time last year. I'll talk to him tonight and see if he's up for joining in on this project.<br><br>Christie<br clear="all">_______<br>Getting to the bottom of the hill is convenient. The view from the top of the hill is stunning. Where would you choose to live?<br>
