Currently, there is no consolidated group for Alteryx For Good where individuals can join as members or post a blog or recent visit post. (I understand co-lab is there but it is very different from the ask)
The suggestion is to create a separate tab under - Alter Nation tab of the community portal similar to Women of Analytics.
This will help all the AFG enthusiasts to stay updated about the news and events happening across the world and also take some learnings from each other's visits and implement it in their respective regions.
This will also generate more excitement about Alteryx For Good and eventually trigger more Good to the community!!!
