Why should I join a mailing list?
As with most open source projects, the community of people using and developing NetBeans are the best resource for getting technical help!
The NetBeans mailing lists are where community members come together to help each other out, discuss tips and tricks, share and resolve problems.
Sharing your knowledge with other list members is also a great way of contributing back to the project. If you see a question on a list that you're able to answer, please jump in and answer it! As a matter of fact, the lists would be useless if they were only for submitting questions, and no one replied. So please help out when you can.
