so you noticed that everytime a user puts a url in your posts, phpbb automatically creates a link for in in the post conent. so now you have all those spammers putting their links on your site and they are not linking back to you. or maybe you want to keep your forums clean. well, there is a solution this is a simple mod you can do yourself.

open includes/functions_content.php

|-----------------------------
Find:

function make_clickable($text, $server_url = false, $class = 'postlink')
{

|----------------------------
Add Below:

return ($text);

so now it should look like this:
function make_clickable($text, $server_url = false, $class = 'postlink')
{
return ($text);


save it and upload to your site. you will see the new post will not have the links but only the url in text. if you have phpbb3 you may have to clear your cache in order for the new data to be refresh.

hope that helps
