Hey :-)

last week i added two articles about editing OpenStreetMap at the webpage of the Andorran Free Software and Free Knowledge Meeting: http://www.andfree.org/creating-maps-on-openstreetmap/ and http://www.andfree.org/how-mapping-in-openstreetmap-makes-fun/

A further article is planned - yet another tutorial to get started with OpenStreetMap.

cheers!
