I'd love to help. Looks like there are a few errors (or outdated items) on the main website, and I'm curious where the repository is--is it available? Thanks!
I think the answer is no, which is a shame. I filed an issue last year about a minor problem with the site, and indicated I'd be willing to write a P.R. if the site's code were public, but it never got a response.
And also somebody needs to add the logo on the left side of a tab.
