Add navigation links to main navigation?

[foxway]

Hello, I'm a recent LJ migrant and I'm using the Tabula Rasa layout by girlrock  located here.

I would like to add or change some of the main navigation links to include an about post and a link to my website or another journal, but I can't figure out how to do it?

 

I can see that she has manipulated the main navigation links in her own journal navigation (the about, fics, and code pages) and from what I can see, she doesn't have a paid account?

 

I've read other tagged entries saying you can do it via S2, but only with a paid account? And I also don't even know where to go to edit the code for S2.

 

I could conceivably try to style the link list module in a similar format, but I wouldn't know how to go about doing that right now since I'm not familiar with dreamwidth coding as of yet. 

 

Any ideas on how I can add my own links to the main navigation? Or change some of the ones I'm not using? Thank you for your help!

EDIT: She was kind enough to tell me how she did it here. It involved creating a new theme layer for Tabula Rasa which I was able to do with my free account easily following her instructions.
