Thinking of contributing

Hey all,

I am a recent CS grad in training to be a security consultant. It has been
suggested to me that contributing to Test the Web Forward would be a good
way to get a better understanding of browsers, HTML5, Javascript, the DOM,
etc. I've got the tests to run locally, and I've looked through the
documentation and at the tests themselves. I have a basic idea of how I
could proceed, in terms of creating tests, but being that I have no
experience with javascript or HTML5 (and not really any front-end web
experience at all), I'm not exactly sure where to start -- ie I don't know
what exactly needs testing (. If anyone could give me some guidance here, I
would greatly appreciate it.

Thanks,

Chris
