Single User Login finalisation announcement/Timeline

Metrics for success:

• Number of rename requests
  • Should increase (due to communications), then decrease down to 0 over time (as those requests are handled)
• Number of clashing accounts
  • Should be monotonically decreasing (as renames are handled)

Rough projected timeline:
