The PHP Framework Interoperability Group (or PHP-FIG for short) has just released a new version of their website with a great new look and even better organization for the PSR content: http://php-fig.org. They just tweeted about it too:
What do you think of our new website? Slicker, cleaner and easier on the eyes. Give us your feedback! :)
The new version of the site provides sections not only for the details around currently accepted standards but also on current proposals, members of the organization, bylaws and frequently asked questions about the group. They also have links to some resources where you can get involved if you're interested in the group and what they're up to.
