Heh, you're welcome :) Scriptspot is a great place ( the best ? ) to find 3ds Max scripts and plugins, most of them for free. I think it should have its place in Wiki.
If you are using 3ds Max, there's a great free script on Scriptspot.com that does the stitching of vertex normals for you. I think it's called Vertex Stitcher or Normal Stitcher.
