Hey guys
All of us who use wordpress love the thesis theme.
Well I am using thesis too 
If u wan’t it add me as a friend in facebook( http://facebook.com/geekxpot) as I don’t want to make my blog a spamming area 
Ok
Here is what you do to remove your footer
This is the footer you see by default

To remove this go to your file editor (in cpanel) or by FTP edit the file named launch.php which is under wp-contents/themes/thesisv1.8.2/lib/functions/launch.php or search it! 

Now add the following code to remove footer

/* Remove footer link*/

remove_action('thesis_hook_footer', 'thesis_attribution');

Now for the custom footer
Add the code at the end of launch.php

/* Add your own footer link*/

add_action('thesis_hook_footer', 'custom_footer');

function custom_footer() {
?>

Happy thesisin and wordpressing !!
