thank you for replays.
No i dont want to change any iner page title for other people. I noticed for my PR4 sites google index other "title" for few internal pages, just asking if around is other type of hacking.
The code source of this pages is unchanged, but google show other title for my important pages, this is very strange...
I know yahoo indexing as title for some pages the keywords for what a page have more back links!
