Well as far as I know, one can only read and copy from pdf files unless u have a paid, licensed version for Adobe Acrobat reader/Writer.
The free version can only read pdfs.
If you want u can create a document(.doc) and mail it to Adobe. they will mail you back the pdf of that..but u need to register, and for each registration u will get 5 free converting chances.
