The CPNP email list allows the members and administrators of the organization to communicate with each other. If you are a member of CPNP, you can manage your subscription as a preference here.
In the member's password-protected area, you can find an archive of past messages sent out on the listserve. The archives are searchable using the website search feature located at the top of each page. If you are a member of CPNP, then you can log in and browse the list archives.
If you have any issues posting to the email list, try to post using the online form.
