How do I change the tags on my blog listing?

When I first got my journal listed on indiblogger, I (must have) specified some tags. Now I relalise that I'd like to change them a little. In particular, I'd like to add the tag 'personal,' because I would like my journal (which is a personal blog) to show up when someone looks at the top-ranked personal blogs on indiblogger.

Could someone help me with how to do this?
