You are right… not very active on Talk. In the past I enquired about updating the https://dallasmakerspace.org/wiki/Photography_Interest_Group page but could not find/get access to it.
We do have a FB closed group here https://www.facebook.com/groups/MakersofPhotos. We are meeting once a month and the SIG is slooowly coming together.
@Nagyk thank you for tagging me… and, by all means, you are more than welcome to be the primary contact
