Let's say I have these groups of donors:
- Small donor, gave < $100 in the past year.
- Medium donor, gave $100-500 in the past year.
- Major donor, gave > $500 in the past year.
What's the best way to get a count of all these in one place? My best thought is to create smart groups - then I'd need a report of "Counts by Group". Does such a thing exist? What if I use aggregation with a Drupal View?
