Hello! I am Martin, I work for the GW Open Science Center (gwosc.org).
I am happy to announce to those working in some way with gravitational wave astronomy that we created a specialized discourse forum for the field!
You can check it out at ask.igwn.org.
At ask.igwn you can open threads on topics related to data analysis, available software, open GW data, the astrophysics of potential gravitational wave sources and other related topics.
Go check it out!
