timethief: using another browser makes no difference, the design of the page doesn’t look anything like the screenshots, so I think it changed, or I’m accessing a different page (http://wordpress.com/#!/my-blogs/).
I also want to leave a blog! It was beter the disign before! I alredy read it in the section og HELP but I did not find “Leave Blog”, I also tried with another browser and clearing my cache and cookies, Help me please.
You are on the wrong page. That is the my blogs off the wordpress.com main page. Go to your dashboard and near the top of the left navigation, click on “my blogs” and there you will find the link to leave a blog when you hover over the blog URL (second column).
