Hi Jeroen,
Absolutely, the user meetings are open to anyone interested in participating! Participation includes just listening to see what others are doing and keeping in touch, and there is no requirement to present anything.
The announcements for the bi-weekly meetings are done on this forum, with updates send the Tuesday before each meeting:
The link above also contains a zoom link and a link to a google doc, where anyone can add discussion topics.
It would be great to have more users attend!
Cheers,
John
