Join us the afternoon of the 20th of March to hang out, enjoy some snacks, and learn how three different rollup tools can help you automatically summarize data where it counts. How many donations did this person donate in the last 5 years? Or how many volunteer hours did someone work last year, 2 years ago, 3 years ago? Or whatever you can think of! As always, it'll be casual, practical, fun, and loaded with tips to save you time and make the most of your data.
