There are several TALK categories that are accessible only to Members; and they aren’t visible to the external crawlers, etc. Anything that is sensitive to DMS, or about DMS-internal operations, should be discussed in one of these categories.
Specifically, the categories are Members Only, Logistics, Infrastructure, and Expansion.
If you need help accessing those categories, this Talk post should give you the specifics.
The most crucial issue is that the email address you use for TALK has to match the email address that WHMCS uses (the billing and member management system).
