So...when you say "document"...
As mentioned a "document" can pretty much be anything. Word™. Excel™. PowerPoint™. The new, free OpenOffice. Templates & macros. Even web pages and other Internet items.
I can create new ones for you. Edit, update or even re-write your current ones. Document conversion and recovery are also available.
I can help you with with animated PowerPoints™, documents with automatic cross-references, merged data and indexes. Plus lots of other advanced areas.
Some people have even got me to "english-ify" their works! I think they made that term up, but I knew what they meant.
