Is it possible to create a page like Special:Preferences that only registered users can view/edit and that is completely user-specific?

My idea is to add a user-specific section to the main navigation where users can add and remove their own wiki bookmarks. But where to store that information? And how to give the user access to it? I could create a User:XXX/Navigation or somesuch but that would be public. Any user - even an anonymous one - would be able to view and edit it. That's hardly ideal. Having the information that a user edited his/her bookmarks show up in Special:WikiActivity (or similiar pages) would also not be particularly useful/interesting for other users.

This cannot be done. Any information you put on your wiki is public.--GodPray  18:21,2/16/2012 

The watchlist might work as a tool for this, I suppose -- RandomTime 18:33, February 16, 2012 (UTC)

Well...that would be an alternative, yes. I could add a menu item "My Watchlist" and write a script that adds the most recently updated items to it... But that still wouldn't put the user in charge. He/she would have no direct control over the menu items. After all: He/she might want to add a page to which he/she doesn't go all that often - maybe because there's no easy route to that page... Such a menu would also be somewhat unpredictable. Speaking for myself: I don't like to use menus of which I don't know in advance what they contain. Pecoes 19:02, February 16, 2012 (UTC)

Browser bookmarks? -- RandomTime 19:07, February 16, 2012 (UTC)

Okay, you got me there. Sure, those are an obvious alternative. But think of it less technically! Think of it as a bonding experience between you and your wiki. Putting all of your tools and toys exactly where you will find them is one of those things you do to feel at home, isn't it? Have you ever worked in an office where the cleaning personal constantly re-arrange your desk? That's what Wikia feels like at times... Pecoes 19:23, February 16, 2012 (UTC)

One of the many reasons I use monobook. I know there's javascript to add things to the sidebar in monobook, there might be similar javascript in the new skin. If there is, someone will probably link to it in a reply -- RandomTime 19:26, February 16, 2012 (UTC)

Do you happen to know how and where that monobook script stores its information? -- Pecoes 20:03, February 16, 2012 (UTC)

Replying to myself: How about a cookie? I would not have to store the page titles or links - only the pageids. That's a measly four bytes per bookmark! Might work... The bookmarks wouldn't be ported to a different browser/machine though. -- Pecoes 20:10, February 16, 2012 (UTC)
