Hmmm, I wonder if this could be accomplished without PGM's active, on-going participation? Maybe a standard could be agreed upon for titling user reported bug report posts so a simple search would return only those? And maybe ask PGM to add a pinned post with instructions for titling your post along with instructions or a link for searching? And maybe PGM could grant forum admin permissions to a trusted, long-term beta tester to edit titles to maintain consistency, mark as Open, Verified, Resolved, etc.?
Just some thoughts from a calm, bugs-don't-bug-me-so-much-these-days guy!
