To add a link to your page to another document within your directory, you only need
to use the filename itself. For example, if your index.html file has a link to
a second page within your directory, you would link it as follows:
<a href="secondpage.html">
You don't need the begining (http:/www.geocities.com/) part at all.
Also, if you'd like to link your page to another homesteader's page, the same rule
applies. For example, if you want to link to 1000 Colosseum, you would write it as follows:
<a href="/Colosseum/1000/">
Please be sure to follow this rule when you design your homepage.
