Sounds like your "stuff" re: Nicky does exist in two places. One is in his Agenda and the other is on your generic W/F card. Your describing D. Allen's system to a tee and I find the W4 list to be, in some cases, not maximally productive.

To quote my first post: "What I don't know is how to keep my Waiting 4's associated with their original agenda." Perhaps, I should have been more explicit. My goal is to have All-Things-Nicky that are moving parts on the Nicky list, so that when I have a face to face or I'm on the phone, it's right there in front of me, in one place. I don't find that it helps the conversation much to have to hunt through my Waiting 4 list to find the 1, 2, 3 or more things I'm waiting for from Nicky. It's inefficient and it's distracting to see all of those other items that have nothing to do w/my conversation w/Nicky.

With a paper system this would be simple. You could use a highlighter -- use a different color highlighter than you use for completed tasks. If your anti-highlighter you could use an asterik, a star... there's a million ways to delineate the Action as a W4 AND still keep the the W4 in Nicky's@context/action - in one place.

However, using ICal is somewhat more limiting in that I can't easily flag them. It would be great if someone had an AppleScript that had a "Mail Act-on" type trigger that colored/highlighted the NA as waiting for.

Thanks for your posts.
