Blogspot user interface is not very intuitive or clear. There are a number of situations where what should be the obvious thing to do, is not the right thing to do.
Here I have some answers which I post recently on Blogger user help forum. I have answers for only the more basic, first time user problems. Please post questions on more complex problems on the forum and wait for answers from our Blog*stars.
Q: How do I find my URL?
A: Please go to your dashboard>settings>publishing>Blog*Spot address
You will see your blog address there.
Another method is to go to your dashboard. Click on [view blog]. Your URL is shown in the address bar near the top of your screen. It looks like this [http://blogaddress.blogspot.com]. Highlight, copy and paste your URL because typing will introduce errors.
