I've signed up but can't see any discussions.
The site as a whole is very active, but the Quilting for Charities group is not a very active group at the moment. Projects occasionally pop up. When they do, someone posts a thread asking for help and we all chip in. I'm not aware of anything going on right now though and I haven't seen any new projects in a while. The last I recall was a quilt for a foster child some months ago.
