Makes me relog in all the time. Odd definition of forever.
Happening to me too, I'll clear my cookies (AGAIN) later to see if it is resolved.
I personally don't like the dislike Kudos, as people tend to abuse it if they don't agree with your opinion. Remember the Sega forums? Oh god how the Sony users neg repped a ton of Nintendo users and it went back and forth.
Keeping it positive only is so much better. That way, if you do something awesome. You get a better Kudos number. This way makes it so no one can abuse the neg rep.
