Extras is dedicated to everything having to do with Underworld that doesn't take place beneath the earth's crust--in other words, things that are real. All of the pages are CONSTANTLY under construction, so if you see erroris, have comments, or suggestions, just email us!

Personal Icons is a page of little pictures that you can use on the Boards, in the UPO, that can represent you as a person, or as a character. Just another way to customize your posts.

Credits is a page thanking and linking to the sites that have helped Underworld become what it is today. So thanks for all of us guys!

Links We Like is a page of links that we as a community think are useful, fun, or anything awesome. They can be other RP sites, websites, or personal pages. If you have a site you'd like to see on the Links We Like page, send them to us at Webmaster@subterrainia.zzn.com, or PostOfficialPrime@subterrainia.zzn.com.

Links to Us page is a page that has banners on display that you can put on your site if you'd like to link back to us. That is, if you like our pages, and want to recommend them, have used our ideas, or pictures, link to us and tell us that you have--we'd like to see our viewer's pages too!

About Us is just a page that tells a little bit about the people who have made Underworld, and contributed to the physical making and managing it. (Under Construction, lol!)
