Mailing list
The mailing list is the primary way we can keep you informed of events. Send an email with your full name and occupation to join our mailing list.
Shanghai list: Send to info(at)ocnetwork(dot)org
Beijing list: Send to beijing(at)ocnetwork(dot)org
We have never sent out spam before, and do not plan to in the future. Leaving Shanghai? send an email to the above addresses with "unsubscribe" as the subject to be removed from the relevant list.

Facebook
We have an Official Facebook group for discussion and event notices. As there are other groups of the same name trying to imitate us, please make sure you join the real thing: look for our red circular OCN logo.
