Roni,

I've trimmed this to the ones I wanted to follow up on.
All else is fine.

OK, that didn't dawn on me.

OK, I take it back. I haven't thought about this for awhile and was a 
little muddled.

Sorry, I didn't look close enough and thought all that text was about 
the captureid.

I think it would be helpful to break these into two subsections so that 
it is very clear that there are two actions called for.
