Reblogging on tumblr?

[skittles]

I'm new to tumblr and I've basically figured everything out but whenever I try to reblog something my name won't show up. Like you know how when you reblog something your name is below the picture or post or something and then there's a line going down that leads to what you said? That won't show up for me. Only the thing I said shows up, but my name won't.
