The easiest thing people can do these days is to take georeferenced photographs with their phones, best with a photo app that will record the direction the phone was pointing, for example OpenCamera on Android. Then take their time and then add the information either with iD (the javascript based editor on openstreetmap.org) on a desktop (or JOSM if they are savy enough), or on either of the mobile editors, but most importantly sitting down in peace and quiet.

While direct entry (on the phone) is what I would do and would recommend for anybody that already knows the ropes, it is going to be overwhelming for a beginner.

PS: I was commenting on the whole thread, and if you look through it you will see Steve mentioned as the OSM savant.
