I had an embedded theme, but you can only have Disqus comments with a full-page theme. The problem with the full-page themes is that they don't have a link back to the home website. So, from within one's site, you click a blog/stream link and go to a page that looks totally different from the website, the home icon on that page doesn't take you back to the site, and there's no other link back to the site. Kind of confusing

I thought you had put a Stream in an Iframe? I know there was some talk on here about using Streams with Iframes, but I haven't found anything about text issues when setting it up that way.
use the code from the stream to embed
Do you mean view source > copy code and paste with the HTML tool? Or get it from the customize > hardcore option then paste that in? If that's possible, that would be great
