Yes, I am new to osm.
I want to add street names to the map in my town.
The opening screen in Potlatch 2 shows on the left a list of points of interest: shopping, food and drink, etc.
How do I add street names?
Have a look at http://help.openstreetmap.org and do a search there for key words like “street” “name” or similar.
