From time to time it happens on a website project that you don't really have pages with teaser- or distributing-functions, but are in need for a first child redirect. In Drupal 7, for example, the most convenient solution is to install the menu_firstchild module and just juse
<firstchild> in your menus.
In ProcessWire, such a quick redirect is much easier. Just use this in a template, for example
* Template: First Child redirect
