OK, five minute job. No error checking, no styling, no nothing.
Use at your own risk.
Create a new file displaypost.php in your wp-content/plugins directory.
Paste the code below into it.
Activate the plugin.
Drag the widget to your sidebar.
Enter the desired post ID and Bob’s your uncle (I always wanted to use that phrase :))
Cheers,
Christian

Thanks for that cschmitt – looks great. I found a work around solution that did the job for me in the meantime. I installed the Executable PHP widget and then used the following code to pull in the desired post:
<?php
$post_id = 71;
$queried_post = get_post($post_id);
?>
<div class=”specified-post”><?php echo $queried_post->post_content; ?></div>
Thanks
