I came across this site which may (or may not
) be of use to you, but thought I'd pass it just in case....http://www.pdfescape.com/Free Online PDF Editor
It allows you to:Add text, shapes, whiteout & more to PDF files
Move, delete, & insert PDF pages
Create links to other PDF pages or web content
Change PDF information tags
Encrypt PDF contents using a passwordAdd & edit PDF annotations (sticky notes)
I think the unregistered options only allow you to upload pdf's with a max of 50 pages (unsure what you get if you register) and of course dependent on your broadband speed if may take a while to upload a BIG file, but if its only text pdf's yours may not be that big.
Anyway, thought I'd pass it on.
ps, see attachment for a view of some of the options.
