[2021] MOVED: how to share waypoints

There are two waypoint lists in the map menu; The top one and the bottom one. The bottom one is 'shared waypoints' that must be manually accepted to your own waypoint list which is the top one. WAypoints are not automatically shoved into other peoples WP lists as it could be abused in various ways.

So your friend'll need to select the relevant waypoint from the bottom list then click the 'add to waypoints' button right above it.
