Release notes:

When you don't want to appear the form login in main page, you will think creat a link for login

Ex: < a href="login.php">Login</a>

after download it, replace folder 'account', and use way:

<a href="<?php echo $vars['url']; ?>account/login.php"><?php echo 'Login'; ?></a> for all area of site

Or use way: Open mod/custom_index/views/default/canvas/layouts/new_index.php

find:

 <?php
                //this displays some content when the user is logged out

                if (!isloggedin()){
                                echo elgg_view("index/lefthandside");
                    //display the login form
                    echo $vars['area1'];
                    echo "<div class=\"clearfloat\"></div>";
                }
            ?>

and replace

<?php
                //this displays some content when the user is logged out

                if (!isloggedin()){
                                echo elgg_view("index/lefthandside");
                    //display the login form
                    //echo $vars['area1'];

?>

<a href="<?php echo $vars['url']; ?>account/login.php"><?php echo 'Login'; ?>

<?php                   echo "<div class=\"clearfloat\"></div>";
                }
            ?>

Have fun
