I’ve raved about the value of extending a personalized welcome to new community members and I recently shared six tips for running a successful hackathon-flavoured unconference. Building on these, I’d like to share the specific approach and (free!) tools I used to help prepare new rOpenSci community members to be productive at our unconference. My approach was inspired directly by my AAAS Community Engagement Fellowship Program (AAAS-CEFP) training. Specifically, 1) one mentor said that the most successful conference they ever ran involved having one-to-one meetings with all participants prior to the event, and 2) prior to our in-person AAAS-CEFP training, we completed an intake questionnaire that forced us to consider things like “what do you hope to get out of this” and “what do you hope to contribute”.
