Take a look at it here: http://www.recursiv.com/threatmatrix
To create and edit pages, you use a special markup language (different from HTML, but a similar concept). I urge everyone who is interested in this topic to go take a look. Once again, I need to stress that anyone can edit and create pages. This gives it a lot of power, because you don't have to wait for an administrator to post the data. If you have something to contribute, then please do so. It would be great if we could get this off the ground. Go there and create an account to start. Please freepmail me with any questions or concerns.
I tried to ping everyone that came to mind, but I'm sure I missed some people. Please feel free to ping whomever you would like to this if you think they would like to use this.
You do great work.
