How add related nodes to content profile? In Drupal 6, I am trying to list the links to nodes created by that user and/or nodes which have her name in their tags below the profile. But I could not figure out how to do either. I appreciate your help.
You can load nodes by various parameters. Just give the parameters which you want to load.
See here Here is for Drupal 6 also.

If you had a code in D6 to load a node using an array of conditions to match against in the database query like this:

&lt;?php
$param = array(
    'type' =&gt; 'your_node_type',
    'title' =&gt; 'your node title',
    'status' =&gt; 1,
);
$node = node_load($param);
