Move Xbox Gamer Tag to Member Meta #28
Description
Currently it's in the Member table and sourced from the Slack Display name. That is no longer accurate, and some member tags are not accurately pulled. It would be easier to make it editable from the profile page and decoupled from the Slack name. This would require also migrating current GamerTags from the member table to the member_meta table. The UI calls need to be considered, so the existing API calls should be refactored, but not completely removed until the UI is updated.
