During a quantitative research we want to be able to link logged interactions to the respective participants. This task is not about changing any banners, but laying the groundwork by changing a schema (and deploying its revision ID to the wikis) to support this.

Acceptance Criteria

• Interactions with banner form elements (not their values) are logged:
  • Selecting an amount
  • Selecting the custom amount field
  • Selecting a payment interval
  • Selecting a payment method
• The schema stores a user ID with the event data

Possible Solution

• Change the Schema:WMDEBannerInteractions to accept any string instead of an enum.
• Apply newer revision ID to Extension:WikimediaEvents.

Notes
We should document a cheat-sheet about how to push code into the extension's repo.
