In Bug Tracker, unfortunately the submitter links merely take you to
the generic (and mostly useless) "Community Member" page for that
user, rather than showing you
all bugs submitted by that
user. But clicking on the right links, eventually I got it to show me
the list of all 13 currently "Resolved"
bugs submitted by Brian.
Looks like they've all been fixed in OpenACS 5.9.1, awesome.
