Did Akismet's pricing/license model change?
Tried to plug in my Akismet api key, got a "The key you entered is invalid. Please double-check it." message. I checked my backup info and what I tried to copy and paste into the field was what I had used on several other sites.
I dont see anything on the Askimet / Automattic site; anyone else having problems using their established API key for Akismet?
