Help Center • From Tumblr F.A.Q

Have questions and doubts about how Tumblr works? This are a few of the F.A.Q. (frequently ask questions) available at the Tumblr website. 

How do I add comments to my blog?
We don’t support native comments on Tumblr, but many of our featured themes let you easily install Disqus comments via the Customize page.

How do I change my portrait photo?
You can associate a portrait photo with your primary and each of your secondary blogs under their settings page. From your Dashboard's top navigation bar, select the blog where you want the portrait photo changed.Then, click Blog Settings on the right side of the screen. Square images that are 128 x 128 pixels or larger work best.

How do I reset my password?
If you forget your password, you can reset it via email. If you aren't getting our password reset emails, we also have information that may help.

What can I do if I have trouble logging in?
Clear your web browser's cookies and try logging in again. You can also reset your password if you forget it. And, we have detailed help available if you have lost or forgotten your registered email address.

How do I block or unblock someone?
You can block someone from appearing on your blog and Dashboard via the Block page. The same page can also be used to unblock someone. Please remember your blog page is still public even when using Block. For greater privacy, you can create a password-protected blog.
