From D&D Wiki
The Acrobatics feat and many others are not listed in the Players Handbook 3rd Edition. Acrobatics is only listed in the Song & Silence guide book. I did not see any update on the Wizards site, where do these feats that are not listed in the PH come from? Need source information.
If others wish to help, this part should be easy. Simply copy any 3.5 feat that has a 3e counterpart and just edit the links to 3e. Almost universally that'll be the extent of the changes needed, though the OGL content is linked on the main 3e page so be sure to verify!21:41, 5 September 2011 (MDT)
