How to add a place + placename to a map

I want to add a placename to a place near my home. It’s not a POI and it’s not a centre of population, it’s just a crossroads in a forest. Using Potlatch I added a dot to the map at the crossroads but the only tags offered are inappropriate ones such as parking lot, hospital, etc. It’s just a place (a Node in OSM-speak).

I’ve scoured the OSM Wikis to find out how to do this simple thing without success.

How do I name my node/place ?

How to do it can be found here in the wiki.

The tags to use are:
place = locality
name = whateverthenameis

Thanks very much for this prompt help.
Greatly appreciated.
