The only edit functions in my global scrapbook block for my title header are to change font specifications--am I stuck with the split-pea soup color of the green salad theme?

I am trying to add a previously created slideshow to a page. I have saved the slideshow in my scrapbook but cannot paste into a block on my homepage...

I have several blocks that I'd like to add to a sidebar on all existing pages of a website. I watched the video, but I seem to be missing the last step . Does this still work in the current version of C5? Or, is there a work-around? Thanks! Alan
