Welcome to Volume 3 of the FRB Community Newsletter. We deeply appreciate our active and engaged readership (over 600 strong!) and look forward to bringing you research news and highlights through 2022. Meanwhile, could you (yes, you!) please help us out with a 3-question survey to refine our demographics? We promise that it will take less than 30 seconds, is non-intrusive, and that the information will be used to help us tailor our future coverage. Please click here, and thank you!
