Hey! Where I can find the list of all Volunteers from 2019?

Thank you @pmchrist! I will send you the list offline (check our Slack). Then you can update accordingly the list in that will be displayed here.

An interesting discussion would be if we want to remove inactive members from that list. Let's talk more in Slack.
