Does anyone know how to add a read more tag to the Fluid Tumblr Theme?

[Azmah]

Our blog uses the fluid theme but there's an issue, it doesn't support read more and that is crucial for our blog. I can't seem to get the tag working and am wondering how; or, is there a better theme to use?

I'm at school right now, so I don't have access to Tumblr. However, you could make your own theme or try inserting the tags you need with JavaScript.
