I've recently learned that I will be taking over community manager duties for an already established, but young, community (4-5 months old). I feel like I have a pretty good handle on what info I need to get from the outgoing CM, but I'm curious to hear your feedback.
(for background, I'm also working as CM on standing up another community at some point next year, and have previous CM experience starting a community from the ground up.)
I recently became the CM for our community and what I would say was the most useful step we took in the transition is that behind the scenes the previous CM sent out a goodbye message to our superusers that then introduced who I was, so those that are most engaged in the community knew the change was taking place and could help support this.
Other than that I would say make sure you don't change the daily routine of the old CM too much at first, until other members become used to your new role on the site.
Best of luck!
Congrats on the new community @BHall
Agree with @amycatling about the importance of communicating with the power users as early as possible to allow the CM to already start building a relationship before the official day one. They might also have a question or two about super user personalities for the old CM to answer
Some ToDos I can think of:
Would love to hear what additional actions you will uncover during your start. Please share them back with the community in this topic
