You should create the Plone.org sprint event https://plone.org/events/sprints/++add++Event
I tried, but still have insuffisicent prvillegues...
Yes, we should fix plone.org. I have all admin privileges to add the item, so I did after Johannes sent me the data.
I just found, "Can view" was not set for Logged-In users explicitly on the sprint folder. so I checked the box. I just do not have a less privileged user to check.
@thet may you add some sprint (to be removed then) for testing purposes?
still: Insufficient Privileges
If I get a moment I can enable verbose security on another private client and try again with a normal user
maybe we should use collective.impersonate for the testing of user permissions
