When I link them to separate pages ( like I usually do with we sites ) it does not like the url unless I use a full url. 

After reading a little more it looks like all the pages should be in the same file.  Is this how the site should be created?  It there anything special you should do if linking to another webpage.

<li><a href="signup.html" data-icon="clock">Signup</a></li>

I guess my question is ' Should all the pages be in the same file?'  And what if you have several big pages should you like to another file?

thanks
