Omg why won’t tumblr let me open someone’s blog without it just being a sidebar on my dash?! It’s driving me fucking crazy!!!! I’ve tried opening the person’s blog by going “open in new tab”, by opening a new tab and then typing in their url, by googling their username + tumblr, and every single time, it adds the “dashboard” thing to the url when I don’t want it to! How do I get around this and just open an actual fucking page??????
