Weight pages under Contributing to doc

Please weight the child pages of http://drupal.org/node/24572 "Contributing to documentation" to achieve the following order:

* Joining the documentation team
* Documentation writer's guide
* Handbook style guide
* Documentation issue reports
* Commenting on handbook pages
* Creating pages in the Drupal handbooks
* Embedded documentation
* Screenshots
* Documentation project proposals and specs

Most important is to group the first 3, in that order, and have them appear first. The next 5 should also be grouped, roughly in that order. Thanks.
