   I'm currently trying to display categories from each post and was hoping to seperate each category link by a comma, except or the last category.
   

   <?php
   		foreach((get_the_category()) as $category) {
   		if($category->name=='Uncategorized') continue;
   			$category_id = get_cat_ID( $category->cat_name );
   			$category_link = get_category_link( $category_id );
   			echo '<a href="'.$category_link.'">';
   			echo $category->cat_name;
   			echo '</a>';
   		} ?>

   Any ideas?

   for instance:

   <?php $sep = '';
   		foreach((get_the_category()) as $category) {
   		if($category->name=='Uncategorized') continue;
   			$category_id = get_cat_ID( $category->cat_name );
   			$category_link = get_category_link( $category_id );
   			echo $sep . '<a href="'.$category_link.'">';
   			echo $category->cat_name;
   			echo '</a>';
                              $sep = ', ';
   		} ?>

   the added code is using a separator string $sep, which is echoed before the linked cat_name; it starts off as an empty string '', and gets set to comma and space ', ' after the first cat_name.
