I can't see other boards' tickets? Why?

Better visibility of information:

We now have a Solutions and Forum area where information will be better categorized and accessible to the community.  Visibility for existing or known issues will be put in the known issues forum where they will be visible to the community and can be followed and open for dialogue to the community.  We have work flows in place to convert individual tickets that have been replicated (or if multiple boards raised the same issue) into a forum topic.  For security reasons, the Service Portal does not allow clients to see other client tickets. Any communication that requires interaction from clients that didn’t originally raise the issue will be addressed via email, or a private forum specific to the customer.
