Hi all,
I registered the domain:
http://geonetwork-opensource.org
today and made the site available through that URL . The IP address is still the same but may change in the future.
http://geonetwork.sourceforge.net also points to the new URL
Hope you all like it. We have some strange config issue still with Apache, causing the site to be slow. Hoe to solve that in the coming days 
Ciao,
Jeroen
