Ok so you know how on Tumblr when you put hash tags they turn light grey and go right under your post? Well they don't do that for me. They just look like normal text, and are unclickable. Is there some kind of secret? I just do after the text #harrypotter #Hogwarts #tumblr. But they don't work right. Help? P.S. I'm new to the site as many may have already guested
