@dcaceres - Hi! Thanks for installing nRelate on your site.
Sorry this is a little confusing, but you can definitely use the Engadget style on your site.
Engadget is a text-only style. To activate this style on your site, please go to your plugin's settings page when logged into WordPress and select "Text" (instead of "Thumbnails") next to where it says 'Would you like to display thumbnails with text, or text only'. After doing that, then you can go into the "Text Gallery" tab and select the Engadget style from there.
Here are screenshots for reference: https://www.dropbox.com/s/btd6swtze16forn/Screen%20Shot%202012-07-31%20at%205.04.48%20PM.png.
Hope this helps! We have a support forum (nrelate.com/forum) if you ever have any questions or need assistance with our plugins.
