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: When you hover over someones username link in these forums, a button
thing pops up (I think it's called a balloon) with links to their
youtube or blogger accounts. How do I put that information in my
balloon thing? I've been trying to figure it out but I can't find the
link to edit it.
A: You will find the answer on this link: http://www.google.com/support/forum/p/blogger/thread?tid=035fb64bd6666dc9&hl=en
