You can also send Shandeh a PM by finding one of her posts and clicking on her name in the box at left (the box that provides personal info about posters).
It sounds like you're in the final stages of your pattern writing venture. That's terrific! You might find some test knitters here, but you'd have to post a picture of your creation, which would "let the cat out of the bag," so to speak. But on the other hand, you probably won't get any volunteers for test knitters unless they can see what they're supposed to be making. At any rate, if you don't find anyone here, I'm positive you can find some people on Ravelry.
