Lets say you're looking at someone's Tumblr. I can only see a select number of posts on the first page of their Tumblr, and can't go back and see older posts. Is there a way to see older things, or does it depend on how that person sets up their Tumblr? Or maybe that's all the posts they have? Idk, is there a way to tell? I don't use Tumblr, please forgive me.
