it’s possible and easy.
But you have to add a few code (that will be overwritten when you update the plugin).

There are (at least 🙂 two ways:
– hard coded (nofollow will be output, always)
– prety cool upgrade (selectable option in the backend)

[The Hard coded way]
around line 588, you will find

$link .= "<a rel=\"nofollow\"";

replace it with:

$link .= "<a";

and you have it! maybe next time you’ll try by yourself! 🙂

[The pretty cool way]
do the Hard Coded method, and continues:

around line 592, after:

if (get_option('sociable_usetargetblank')) {
	$link .= " target=\"_blank\"";
}

write the following:

if (get_option('sociable_usenofollow')) {
	$link .= " rel=\"nofollow\"";
}

around line 782, after:

} else {
	update_option('sociable_usetargetblank',false);
}

add this:

if (isset($_POST['usenofollow']) && $_POST['usenofollow']) {
	update_option('sociable_usenofollow',true);
} else {
	update_option('sociable_usenofollow',false);
}

around line 834, after:
$usetargetblank = get_option('sociable_usetargetblank');
write:
$usenofollow = get_option('sociable_usenofollow');

and finally, around line 924, after:

<input type="checkbox" name="usetargetblank" <?php echo (get_option('sociable_usetargetblank')) ? ' checked="checked"' : ''; ?> /> <?php _e("Use <code>target=_blank</code> on links? (Forces links to open a new window)", "sociable"); ?>
		</td>
	</tr>

write:

<tr>
		<th scope="row" valign="top">
			<?php _e("Use 'nofollo' rel tag:", "sociable"); ?>
		</th>
		<td>
			<input type="checkbox" name="usenofollow" <?php echo (get_option('sociable_usenofollow')) ? ' checked="checked"' : ''; ?> /> <?php _e("Use <code>rel=nofollow</code> on links? (Forces search engines to 'not follow this link' because it's outside our site)", "sociable"); ?>
		</td>
	</tr>

and you will have the ‘followed’ 😉 option in your Backend.

do backups, and let the force be with you 🙂
