Hi Brent, I've suggested to Lorelei Lingard that she and Hongxing Qi might write the article you're looking for (in relation to SFU's 810 and 802). I think one or both of them would probably like to do it. But Lorelei just had a baby, Hongxing is just recovering from an illness (and neither use e-mail much). How soon do you need what? Rick Coe
