I bookmarked the dashboard fr SE: http://www.blogger.com/blogger.g?blogID=542518648627849085#allposts
Just plain old www.blogger.com/home takes you to the same place.
I like going right to the post listings, since I can see if anyone commented easier.
If the post you are commenting on is more than 30 days old, your comment will have to await approval before being published. Rest assured, however, that as long as it is not spam, it will be published in due time.
