OK, I see what you mean. I read it too fast the first time and thought your "rest of processing" bit was inside the first while(). My bad. Yes, you'd need 1..20 for this technique to work.

I didn't see this response due to a config problem on my part. Now I know what "some notes below your chosen depth" means, sort of. I had not set a depth and assumed that I would see all responses in a thread. Apparently not.
