Sorry it took me so long to get back to you - I've been buried under projects and haven't had a minute to myself.

I'm not sure what levels of participation you're looking at, but at the minimum I can stayed involved in an ongoing email dialog. More participation will depend on what's needed and what I'm working on at the moment. ;) >2) send me a list of what you think are the most important fundamental >issues related to 3D/immersive manipulation that need to be discussed >and written about - We need to forge stronger collaborations with psychologists.
