Enable the Ask Box
Click the gear icon on your dashboard. You must be logged in to your main Tumblr account to perform this action. Select the tab for the blog on which you want to enable your Ask box, and then locate the Ask section on the settings page. Toggle the switch next to “Let People Ask Questions” to “On.” The switch changes from gray to blue. By default, Tumblr enables an Ask page at the URL with the following syntax: http://yourblog.tumblr.com/ask Replacing “yourblog” with your blog’s name. Enter a page title for your Ask page in the Ask Page Title field. To allow anonymous users to send you asks, toggle the switch to “On” next to “Allow Anonymous Questions.” Tumblr automatically saves all of your changes.
