  1. Role Refresh: Set to run nightly
  2. Fundraiser Synchronization: Set to run nightly, and possibly often for right before the event
  3. List acquisition and refresh: Set to run no more than every 20 minutes
  4. User Imports: Set to run nightly
  5. Email: Every one minute
  6. Raiser's Edge Integration: Should be set to no less than every 60 minutes
