A: If you use the word "updating" it means that you have a blog with some contents in it in 2005. It is apparent to me that you have created more than one account. On your dashboard now, if you do not see your blog, please do not click "create a blog".
Unlike other blogging platforms (word press, my space, typepad, livejournal, multiply, facebook, friendster, hi5), on Blogger, we do not call a blog, a blog. When you wish to make a new blog, you should click on "new post". Other wise you would be creating blog after blog and not posts; just like this one here:http://djlaura.blogspot.
If you do not see your blog (It ain't over 'til the fat lady sings) on your dashboard after signing in, you are signed in to a different account which is not associated with this blog. Similarly, you could have created more than one blog and you could have created more than one account.
You can spend a long time sorting out your accounts.
