There are only 6 themes located in my "Presentation" "Editor", none of which work for my blog. I really like the "Trees" theme I saw in Theme Viewer ID:890 but can't figure how to upload it. I downloaded the zipfile to my desktop and when I open it there are like 15 files. What do I do with these to get them into my "Presentation" area of my admin so I can change the look of my site? Thanks.
