I have edited and corrected a place name on geonames.org. What happens with my update if a new nga release is loaded? Will my update be overwritten and disappear?
Your update will stay untouched.
First we only update nga records if they have a timestamp newer than our last update, and second even if it has a newer timestamp we compare the change history for both update branches and the two branches are merged whenever possible. If it is not possible to reconcile the two conflicting branches the modification by the geonames user takes precedence.
The concept is similar to the 'progressive fork' concept of the wikipedia fork Citizendium.
We are also in touch with nga and send them periodically our updates. It is therefore possible that your change on www.geonames.org makes it into the official nga release.
