Steve, and all, I think you are doing a great job; make no mistake about that!
I apologize if my prior post sounded derrogatory - it was intended as an observation only, not a complaint. Typos in general are common with almost everyone, myself included. These questions just are a bit more technical, and the difference of one dot or title is a make-or-break truth.
I actually think this is a mark of achievement: if nobody complained about it, the site would not now have the prestige it currently does. Users enjoy collecting points and grumble when a dot or title chaps them out of one. I look up to those with 2K+ points... lot of contribution there. And, it seems to prove that user submittals and participation is valued.
(grin) Keep up the good work!
On the history of questions, I think the potential frequency of duplication is very low, and would have no impact and user experience here... so I guess I will quit worrying about it and try one...
