Proposal for MobileWikiAppCreateAccount2 (no sampling) in order to be able to answer the following questions:

• whether people have made accounts through the app
• verify that the account was made through the Android app specifically
• whether people continue using these accounts in order to edit (both through Android app or on web)

Spec draft:

• last_status
  • example values:
    • "start" if user went into "Create an account" screen but then cancelled
    • "captcha" if user saw a captcha but did not finish the process
    • "finish" if user successfully created an account
  • Notes: "start" and "captcha" are different steps at which the user abandoned the process
• source
  • how user came to the process
  • examples:
    • "rl-sync" if they tried to enable reading list syncing
    • "menu"
    • "onboarding"
    • any other possible values???
• (maybe) user_id of the newly created account, may be null if user did not complete account creation process
• provided_email: a Boolean flag indicating whether the user provided an email address when signing up
• app_install_id
• client_dt

Instead of the user_id field, it would actually be a lot better to store information in the [[ https://www.mediawiki.org/wiki/Manual:User_properties_table | user_properties table ]] indicating that the account was created on the Android app. The Growth team uses this table to store survey responses, so maybe we could also?
