The PHP Women user group has made an announcement today on their site about a partnership between them and the DevChix to help provide mutual support to each other.

Working together we will hopefully be able to do much more then we would do apart. [...] We at PHPWomen eagerly look forward to working with DevChix and are excited at what we can do together in the future.

You can find out more about the DevChix group from their website including their own PHP section and their announcement about the partnership too.
