Now, I understand. The "Help" documentation does not have this page. Perhaps a link was not correct at the time the documentation was compiled for version 4.2 build. We checked all links, and tried to verify them all, but it is a lengthy and repetitious task. I am sorry if we may have missed that one. We should probably verify that the link for that page is correct so it does not happen again.
This brings me to the question of updating the User Documentation perhaps we should be looking at the change log and making sure the current
documentation remains unchanged.
Also a number of plugins need revisions/improvements to documentation including
weather_routing, weatherfax, watchdog, ODraw, NmeaConverter, etc.
We need some User volunteers to help!
