The one step that I think would help the problem you're trying to address is something I've suggested before: add a permissive "robots.txt" to appdb.winehq.org, and make the one on "bugs.winehq.org" more open. That would probably lead to fewer duplicate bug-reports as people find similar postings using Google or Yahoo.
I noticed your first patch. I had a lot of trouble due to the caching change patch you submitted previously and since I didn't have time to verify the robots.txt change carefully I've just put it aside for now. If Tony or someone would like to check it I'd be happy to put it into the repo, I just don't want breakage like last time.
