Umm ... not sure if I totally know what you you're looking for, but ...
$result = mysql_fetch_array($connectionResource);
extract($result);
print '<a href="forum.php?row=' . $row_title . '">$row_title</a>';
If you've got a many links to create, just put that in a loop.
Then, forum.php will have to access the variable $_GET['row'], and display the appropriate data.
