Access to Sage Implementation Resources

SUGGESTED

Hi. We are a Sage Business partner looking to access the Sage Implementation Resources that contain the "Sage X3 N.A. Customization Library". That apparently is (or was) a Group within Sage City. I cannot find the group to post a question and ask for joining it.

How do I join the group if it exists, or where are these resources located? Specifically looking for the XA101 and XA108 resources used in automating emails, which reportedly are in that library. Any help will be appreciated.
