I subscribed to a thread - I'm getting the notices and can read the posts one at a time in "my choralnet -read my subscriptions"

 

So now when I am reading the actual thread (not in "My Choralnet" where they are one at a time with a "hide" button - the thread all on one page),  the button shouldn't say "Subscribe"  - that's confusing, because I am already subscribed.  It should either be ghosted, or say "You are subscribed to this thread" or something more articulate than that.
