OK, its saturday night here. But that does not mean I'm drunk. Just that I can' remember my adsense bookmark leading to a premium login. I never use my bookmark for accessing adsense, but today I did it by accident. I was going to visit another page in my bookmark-list. I have not got a mail from google saying "mate, youre a premium publisher". Can anyone enlighten me here or is this a "report it to adsense support issue"?
If you don't know something, ask google https://www.google.com/adsense/premium-login seems to be the URL. But once I logged in, I didn't noticed any difference in fact
