Thanks for raising this question, Mohan!
How about integrating your list with the wonderful collection of openacs documentation Jade has compiled over on the openacs site?
For user docs, I would also suggest that we integrate these sites to reflect whatever structure Malte might set up with his proposed context-dependent help system, and also, that we make this interactive, maybe including a forum format, so we could more freely share quick "how-to's" rather than always face editing burdens?
