Footnotes

[Richard Beeston]

Dewar Users.
I need to do a business presentation with footnotes instead of a bibliography 
at the end of the paper.
I am using Windows 7 and AOO 4.1 on a desktop
I know how to put the footnotes in but am wondering how to reference the 
footnote in the text if there is a special format that will automatically open 
the footnote reference if it is a website?
many thanks
