Posting new content to Tumblr can be time consuming, but if you have a secondary blog you can ease the burden by appointing more admins. Unlike members, admins can invite or remove users and delete posts by other members. Co-admins are also allowed to make changes to the settings of your blog. Before you can promote someone to an admin, she must first be a member of your secondary blog. You can invite someone to become a member of your blog even if she is not a Tumblr user yet.

Step 1

Sign in to your Tumbler account, and then click the down arrow next to the name of your primary blog.

Step 2

Select the name of your secondary blog from the list, and then click "Members."

Step 3

Type the email address of the person you want to add, and then click the "Invite to this blog" button.

Step 4

Click the "Promote to admin" button next to the name of the person you want to add as a co-admin.

Step 5

Click the "Promote user to group admin" button to confirm that you want to permanently allow the user to administer the selected secondary blog.
