I've accessed the TAXII Discovery endpoint, and based on my account I get back three collections:
The group one showed up after creating a private group, as expected.
However, I am both subscribed to pulses and have added pulses to my group, and polling the group_* and user_* collections yield nothing. I only have some indicators that come back from the user_AlienVault collection.
Are the group/user collections supposed to be populated with data? If not, why are they even there?
