Commons trunk category (5 first levels) at 2019-06-20
Please do not create categories without checking that there is at least one that is right for you.
If you really think you need to create a category, try to follow the spirit of the category tree here, and, in any case, the categories must belong to the main shaded categories (first or second level in the tree structure).
In the common atys.wiki.ryzom, some rare categories are hidden to avoid spoil.
