Per your message on wiki chat:
 * "how to design signatures"

Signatures are usually built with html. There are many different signatures for public use (including mine), as well as a couple of tutorials. Monchoman45's is popular.
 * "make admins"

You can change user rights (if you yourself have the necessary rights) at Special:UserRights.
 * "put a background on a wikia"

You can use Special:ThemeDesigner to change the background, or you can use CSS (which is more advanced).
