A Rev Web Project and On-Rev working together?

Thanks Sarah and Bj?rnke!

I had a funny feeling about the ":" colon after URL....however, I could of swore I lifted that script from one of the examples, and it had a colon in there...  In any case I removed it and it worked fine :-)

Bj?rnke, as for copying the sentence to the clipboard, is there a technical reason why this is a bad idea, it's not being written to the harddrive? Is it because the user might have been saving something else on the clipboard and that action replaces what they had previously saved?

I was using the copy to clipboard as a kind of cheat. 

I'm going to embed the rev project into Drupal web page.  Originally, I was hoping to figure out how to have the Rev app automatically post an anonymous comment to the Drupal page (the little rev app was embedded in.) But not sure how I actually would do it. Ultimately I was looking for a way the user would be able to share a sentence that they create by dragging a few words from some song lyrics.... I know it sounds a little lame, but I was just going to use it as example for some teachers as to what these tools can do all together. I was hoping to have the Rev project duplicate the process of the Drupal comment action, using the Rev interface instead of the Drupal interface...but still having the user's work show up in the comments section.

As an alternative I may just load a new Drupal Module that pulls a static html file, ...one like Rev creates in my example here. That might work to if I move a way from having the user just past their comment off the clipboard.

Thank you!
