If you want to make changes to your Tumblr blog, there are a few different ways you can go about it. The easiest way is to use the “edit” button on the upper right-hand corner of any post or page. This will take you to a page where you can add, delete, or change the text of your post. You can also use the “edit” button on the main dashboard of Tumblr.
This will take you to a page where you can add, delete, or change the settings for your blog. If you want to make more drastic changes, such as deleting your blog entirely, you’ll need to contact Tumblr support.
