Description of problem: It's a pretty common problem to tell someone, look at this bug xyz and have them say they can't see it. It seems like it would be nice to just have the bug display "WORLD-VISIBLE" or "PUBLIC" or something, somewhere, so you could easily check for that. Sometimes even if all the group checkboxes you can see are unclicked, people still can't look at it. Workaround: You can log out of bugzilla and try to look at the bug yourself, but that's definitely more work.
Red Hat's current Bugzilla version is 2.18. I am moving all older open bugs to this version. Any bugs against the older versions will need to be verified that they are still bugs. This will help me also to sort them better.
It seems to be true now that if none of the checkboxes are checked, the bug is world-visible. Closing.
