I know once a page is edited in BC, it no longer can be worked on in Adobe Muse. Would this affect the entire Muse website/all of the pages in a Muse website? Or does it only affect the page that is edited?
This would affect every page because Muse and BC doesn't have an end to end editing workflow. You'll need to continue editing within BC if you have the option enabled.
