It would be nice if users could 'check in' when they attend certain events together like Alteryx Inspire, Tableau Conference, or a local community event.
The event people are checked-in to could be posted as a status next to a user's name (ex. JoshKushner - at Alteryx Inspire 2018) and popular events could be summarized on the community home page.
This could publicize to other community users meet-up opportunities they might not have been aware of and could facilitate community engagement in real life.
