Welcome to GDS!
I love fonts and I have collected many to play around with.
How you install fonts depends on your operating system -- not your scrapping program. I have Vista and like you I keep a folder in my digi supplies folder titled Fonts.
I open two folders, the folder where I have my fonts (make sure to unzip them) and the folder in Windows that is "fonts" (should be something like C:/windows/fonts)
I copy all the new fonts I have snagged, and then drag them over to the "fonts" folder and paste them.
Once you do that, you should be able to see your new fonts in Elements, Word, Outlook/email.
Hope this helps
