Recently I’ve worked to archive some google mailing lists that I believe are not being used anymore. Let me know if you find something that I mistakenly archived.
I also suspended OpenMRS emails from those who I believe weren’t using and are not active in the community anymore (plus ignored my notification email). If you were on a holiday/vacation across the globe without internet access and couldn’t answer me back before, you still have the chance of doing so. I will keep suspended users for a couple of months before deleting them completely, and I’m quite happy to send you the data if you prefer.
