Hello,
Wow - your presentation is fantastic, thanks for that!
We can definitely use all the help you are willing to provide. You are welcome to contribute to the wiki, forum posts, blog. As far as documentation, you are right we have quite a lot, but I think we can use always more tutorial-type explanations, since our Wiki typically focuses more on explaining how things work, as opposed to tutorial format. Also, code samples are always welcome, if you happen to come across something.
Our community manager is Nancy Garrity, and I just forwarded her your post, so she'll probably reach out to you as well.
Cheers,
Jean
