Thread:Project:Support desk/Hierarchy Extension

MediaWiki 1.17.0 PHP 5.3.3-1ubuntu9.5 (apache2handler) MySQL 	5.1.49-1ubuntu8.1

http://www.mediawiki.org/wiki/Extension:Hierarchy

Regarding the above extension; I am seeking anything even remotely similar to this. A hierarchy structure to manage and organise my entire wiki - preferably, the possibiliy of multiple hierarchies within the wiki to exist separately yet side-by-side - it is a collection of manuals and instructional information - so, one hierarchy would be tutorials, and another would be the actual details and specifics of how and why the products work.

Please feel free to reply with queries if any of this needs clarifying, and many, many (MANY) thanks in advance for any help.

All the best x
