Cluster
Also available in Deutsch[link1], Español[link2], Française[link3], Русский[link4], 简体中文[link5]Wacko Clusters -- Hierarchies in WackoWiki
It allows pages to be divided among "directories / name spaces" using forward slashes and a method of addressing that is typically used with URLs. A cluster refers to all pages within a certain namespace.
Rules of simplified addressing:
-  Link to the current page
- If a link to a page must be made on that same page,
 -  the notation 
!must be used 
 -  Link to a page at the same level
- if a link to ../English/TwoCharacterRule must be made from this page,
 -  write it this way: 
TwoCharacterRule 
 -  Link to a page that is lower in the hierarchy
- if a link to ../English/Cluster/SubPage must be made from this page,
 -  write it this way: 
!/SubPage 
 -  Link to a page that is higher in the hierarchy
- if a link to /News, which is one level up in the hierarchy, must be made from this page,
 -  write it this way: 
../News 
 -  Link to a top-level page -- just as in good old DOS
- if a link to /ToDo must be made from this page,
 -  write it this way: 
/ToDo-- just as in Documentation[link6]
