I’ve upgraded to 2.0 without a problem, signed up with wordpress.com and got an API key (whatever that is!), but when I try to activate Akismet it tells me that the API key is not valid. What am I missing?
Hmmm. I’ve contacted the developers that time, they asked me to email them my API key, but by that time which is about 5 days later, mine is working already. So, maybe after a few days it’s still not working, contact them?
