Netbeans has just started its Community Acceptance Program (NetCAT 7.0) for Netbeans 7.0. Basically developers who are using Netbeans as their IDE need to download latest builds and report bugs. Good experience to get involved with testing and learn more about Netbeans. Also makes some friends with community and developers at Sun Microsystems.
Helps improve the IDE you use daily!!
