How do you edit PDF files?
.. I don't because I'm not willing to:
- use non-free operating systems that are able to run Adobe Acrobat
- install KDE to have KOffice
So yes, having PDF editing capabilities in OpenOffice.org would be nice, but anyway: PDF is designed
to be a final-form of the document.
But I agree with Erwin that for creating PDF, OpenOffice.org is good enough. And it is free.
