PHP nuke

[rakuenso]

Hi, I'm a newb to the PHPNuke and general PHP world, so I've a few questions about how to accomplish the following:

 

I'm planning on making a science site, by creating the modules for Biochem, Genetics, Immunology etc. etc.

 

Now, when I go and create the modules, I wanted so that it displays only the news that are labeled with their respective categories, (Immunology module would display only news that are categorized as immunology and not others)

 

Anyone might be kind enough to tell me how I might go about doing this?

 

My AIM is windig0zz if anyone wants to contact me.
