Wikidata:Subpages

All of these pages are your user pages or user space. While you do not "own" them, by custom you may manage them as you wish, so long as you do so reasonably and within these guidelines.

You also have subpages ending in .js and .css to store any user scripts and skin customizations that you may wish to have when you edit Wikipedia. Only you and interface administrators can edit such pages, although anyone can view them.
