OAuth (obsolete info)/User stories

This is a place to collect user stories for OAuth. Here are the hypothetical users for the stories:
 * Richa - a steward and administrator on several projects
 * Skye - an experienced editor with a good reputation on wiki, but no special permissions
 * Caroline - a beginning editor, with less than 100 edits on her home wiki
 * Clay - a Wiki reader without an account
 * Jimar - a feature developer setting up a wiki on Labs
 * Bao - a Gadget developer

User story: Labs testing for editing
Skye has heard about a new feature in development, and found out that the feature is available on Labs, being developed by Jimar. The wiki is at unicorntears.wmflabs.org. Skye would like to test this feature, so visits unicorntears.wmflabs.org. Jimar has configured unicorntears not to allow anonymous editing, but has configured it so that anyone with a valid CentralAuth account not blocked on mediawiki.org can edit. Skye clicks on the edit tab, is directed to a login page on mediawiki.org. After she logs in, she is redirected back to unicorntears, where she can edit.

User story: Allow a 3rd Party tool limited access on a user's behalf
The website instacommons.com allow users to send their pretty pictures to Wiki Commons automatically. Caroline registers with instacommons.com, then clicks a button to grant instacommons.com limited access on her behlf. She logs in to Wikicommons, approves that instacommons.com can use the "Upload Files" function on her behalf for a particular time period. After this, instacommons.com recieves a token that allows it to upload pictures for as long as the token is valid. Caroline is confident that instacommons.com doesn't know her Wikimedia password, nor can instacommons.com make arbitrary page edits on her behalf that could harm her reputation.
