"OpenOffice already has over 100 extensions to choose from, most
of which are business-related. You can add extensions that help you
create business reports, reduce the size of presentations, or
publish your documents as wikis. Wikis are often used by business
teams now, but many people get discouraged because they find wiki
formatting difficult. It's "absurd," says Suarez-Potts to spend
longer formatting a document than writing it, so the wiki extension
saves people the hassle.
"Suarez-Potts's favorite extensions include a PDF tools that
lets users import and edit existing PDFs, and a calendar and e-mail
client with Outlook functionality. He anticipates a huge slew of
new extensions by the end of the year, as more developers create
ways to link their applications to OpenOffice."
