In Emma's words: 'We encourage users to contact us if they have questions or find problems with the software. New contributions to the software are also most welcome. You can contact us by opening an "issue" on Github (https://github.com/SuperDARN/rst/issues), or alternatively by email.

The RST 5.0 release is a major milestone for the Data Analysis Working Group, and I'd like to thank everyone who has contributed. This is also time for me to announce that I have stepped down as the co-chair of the DAWG as I will be starting a new job in January. We welcome Adrian Grocott (Lancaster University) as the new scientific chair of the DAWG, who will co-chair the group together with Kevin Sterne (Virginia Tech).'
