When we started ICTE it was always mostly done on IRC. Of course then the RS wasn't dying out, the SV was around and so was the GE (was around 4 or 5 years ago). As far as I've seen RS is dying SV is gone, GE is barely hanging around, no idea about NR5f, EH is what it's always been- mostly internal and with 10% as many members as they say, and DB is going strong. Wouldn't be surprised if it's not still around.
