In case you missed it, Volatility 2.0 has been released! Please download it and test it out and let us know if you have any problems via the "issues area" of the Google Code project. We have lots of documentation and for those on Windows who don't like to install Python, there is a standalone executable available in the downloads section. Make sure to check out the FAQ wiki which contains information on what is supported and how to use MHL's malware plugins.
Some OMFW materials have been released:
Moyix's slides (pdf).
MHL's Stuxnet blogpost and slides.
My slides (google docs)
You can help with the development of Volatility by giving us suggestions for plugins, writing documentation or donating malware samples. Check out the FAQ for how to do all of the above.
