A couple of observations from today:

I am logged in to steemitstage.com using my "posting" key.

Today I tried to leave a comment below an article, and received this error message:

"Missing Posting Authority creatr"

Is this correct behavior?

Also, when I have tried to up-vote articles and comments, the little circled (^) symbol does not turn blue until I refresh the page.

And now, trying to Post this Reply, I get this error:

"Transaction broadcast error."

I will cut/paste this using the standard UI so you get the message... ;)

UPDATE I tried again, and this posted... Now trying an edit...
