Re: [wsn] Addition to 20040729-wsn-minutes- we missed start of Thursday's meeting!

[Jem Treadwell <Jem.Treadwell@hp.com>]

Alan/All,

My apologies - Bryan sent me his notes in text, and I copied/pasted them 
into the Word doc, but I somehow chopped the top off them.  I'll upload 
a corrected version tomorrow, and I'll include Alan's notes as a supplement.

Alan, thanks for spotting this, and for the additional data!

- Jem
