OK, I figured it out! You have to COPY (or cut) OUT of the Su2pov35 folder everything in it and then paste that into the plugin folder exactly as it was in the Su2pov35 folder.

NOT just drop the entire Su2pov folder into the plugin folder, ONLY the contents.

I bet it must be quite tedious to hear that question a lot.

I have downloaded sketchup 8, and downloaded SU2POV, and dropped the Su2pov35 folder intact with all its subfolders inside into the plugins folder according to instructions. In the sketchup 8 menu bar I don't see the plugins drop menu just to the left of the help drop menu as is shown in the tutorial's picture. Is that only on sketchup 7 or does it work on 8 as well? If this only works with 7, where would I find a copy of that version?

I hate to appear so dumb, but I can't figure this out. I feel like I am really missing something very obvious here.
