This here above is token from the install-guide (as I call it 2day 
) .
If I get this right (its written in some sort of telegram-style ) the steps should be like this (correct me for I might be mistaken ) :
1- Upload 3 files , the first 2 into the usual forum main dir. ? And then the last one in the forum/img directory ?
2- Open the post.php file that was already made with the implementation of the punbb forum ?
3,4 - I should find line 455 of the post.php file and add this line afterwards :
<?php include("post_smile.php"); ?>
5,6- I should find line 457 and replace it with another line that was given in the doc. ?
7- I should save and upload the newly manipulated post.php and overwrite the old one on the server . This should not affect the posts that people have made earlier on .
This took me 5 minutes to find out what it said .
** suggestion **
Maybe you should explain more details in the install-description ? The PunBB-installation was very easy due to the fact that it had a document understandable for even the most total n00bs on this planet (including me some time ago) .
I would suggest (do not see this as a offensive attack or anything) to rewrite the installation-guide so that even the total n00b understands it .
I'm thinking of trying this one on my forum as well . 
Good luck on future projects m8 ... and keep modding
. My swedish is bad :$ .
