It appears there has been a slight change of heart for Project Kenai so ignore the previous post on Project Kenai shutting down to the public. It seemed it was destined for internal use in Oracle and users were told to move their projects before April 2nd but now the message has changed:
Our plan is to shut down kenai.com and focus our efforts on java.net as the hosted development community. We are in the process of migrating java.net to the kenai technology. This means that any project currently hosted on kenai.com will be able to continue as you are on java.net.
If you have a project on kenai.com it might be best to stay put and wait to see how the migration goes. This decision by Oracle makes the most sense considering the amount of work that has gone into integrating the Project Kenai infrastructure with NetBeans.
