They had an old forum Welcome to the Gene Pool! Please Introduce Yourself .
The community used to be so strong and technical back in 2012-2013 (they also had two conferences at HMS in 2012 and 2013), but the community is in hibernation, and there is so much link rot. Many of the old links are now dead.
They had a hackathon in July 2018 that was quite fun, but even the google drive folders to it are now dead
Still, some of the cell lines were used in publications.
allofus.org tried to continue some of the effort, but its still super-lackluster.
Redirecting is a recent publication using 120 of their cell lines…
at least its Facebook group (not updated in a long time) still exists…
