Way to see activity for all the Tumblr blogs in one place

Mehper's answer no longer works, as Kirk Woll mentions. As of Feb 2015, you need the following URL to edit:

https://www.tumblr.com/edit/<post_id>?redirect_to=%2Fblog%2F<blog_name>

Replacing < post_id> with your post ID # (example: 406783219) and replacing < blog_name> with the domain of your blog, without the tumblr.com part (example: staff).

https://www.tumblr.com/edit/406783219?redirect_to=%2Fblog%2Fstaff

Obviously, you have to be logged in to your account first, and have the appropriate edit permissions.

Your blog has been suspended. Check to see if you are in violation of Tumblr's Content Policy.

If you are found to be in violation of any of the below policies, you will receive a notice via email. Unless you explain or correct your behavior within 72 hours, your account will be suspended. We will do our best to work with you and ensure a fair outcome in all cases. We reserve the right to immediately suspend, without notice, any content, account, or IP address which we determine to be systematically generated, spam, or potentially damaging to our service or infrastructure.

When your account is suspended, public access to your content is blocked, and your Tumblr URL (and custom domain if applicable) is redirected to the Tumblr home page. Access to your Tumblr Dashboard and the ability to add/edit posts is also disabled.

Additionally, check to see if you received an email from Tumblr to the address you signed up with.
