Many users have hundreds of local pages which now hide their global user page. If you're one of them, you can request the deletion of your local user pages on all wikis by Synchbot[1]. You can see a list of local user pages using a Tool Labs tool[2].

For reference, the Wikimedia-specific documentation for global user pages is on Meta[3].
