Besides the obvious contributing to EH.net, what are some ways that you guys contribute?

I believe that one of the best ways to learn is to teach. I also want to contribute to the community from which I have gleaned so much. I'm looking for some input and I thought it may benefit others and the community in general.

Hey Tim...

I saw a very good talk on this by kevin jhonson of SANS, he recommended instead of off the bat starting your own project... help with someone elses!

Maybe a talk at Dojosec?

Maybe Submit some videos to theacademypro.com ?

Find a smaller con and co-present?

Whatever  you're good at i bet theres someone there who can utilize your talents, start emailing people like crazy! bug don! do a review!

One thing that stood out to me when i took Ed skoudis' class was that you can do research in anything. One of Ed's big published research was comparing IDS's. They rounded up a bunch of different versions of metasploit and threw well known exploits at brand name IDS/IPSs, and wrote an expose of which failed some high risk detections (as well as some WELL known ones)... really sometimes its that simple.

One thing i'm gonna do when when i get some free time, (god knows when my kid will give me some is do a real security lab setup walkthrough. As much as i love Micheal Gregg his book left much to be desired.

just my 2c

Sounds also like a similar idea i have had, mine is set on the CEH but more on security in general... great minds think alike!
