Part 3 (waypointing tools) is in the file-base now, along with an off-line version of Denny's RTCW tutorial (for comparison...)

Note it lacks the help articles for Hobbit's waypointing tool. Those will take some digging to see if I have any old copies offline.
Update: it looks like I may only have the last 5 of 11 webpages of the Waypoint tool guide, 3 of which I saved in mht which will take a little while to convert back. So I'll leave it out for this month.
