Argentina Airspaces/Airports

Hi,
I've noticed some errors on airspace definitions and some incomplete data (missing runway information, etc.).
There is a KML map with a lot of correct data which I could download and tag appropriately.
How could I submit this in order to correct the current navdata on flyisfun?
Also, when importing the KML data, will I have everything duplicated with data on original database or how can I deal with this?
