Categories are used to classify and organise articles, to relate them to each other, and to grant or restrict access.
From this page you can browse all categories. The [+] will open a list of subcategories. A click on the category name will take you to a description and to a list of all pages in this category.
Categories are explained in the SPIRIN:Index
Categories are for internal use
Many categories are in use, and every participant can create new ones. Please place a new category in at least one appropriate other category. Otherwise it will end up among the uncategorised categories.
