"Pattern Changes and Designers' Journal" (mostly seems devoted to sewing)
Ample-Knitters web site. Go to Gallery to see photos of member projects. There are also group projects. The email list is good too, but it gets a lot of traffic.
I found this tip about shaping and resizing on a web bbs somewhere:
The directions in the first chapter of SNBN explain the "magic formula" and how to find stitch ratios and row ratios. Seems like it would take a little bit of math, but you could change a pattern to fit yourself if you took your time and worked it out. And just like for anyone who tries to modify a pattern, no matter what their size, it might not be perfect the first time, and might take a little fiddling with as far as when/where to do decreases/increases, etc., but once you had it all tinkered out, it would be awesome and it would be YOURS.http://www.lionbrand.com/patterns/khs-quickVest.html
