What's in the core was added because people requested these features. Sure, we can offer information on how to remove specific components. They are not "too integrated in the core".
Let's take the forum for example:
1. Remove the links from the navigation and the sub-header
2. Completely remove the folder
/forum/ from your webhost
3. Remove the following files from the
/administration/ folder:
forum_ranks.php,
forums.php,
forums_prune.php and
settings_forum.php4. Also remove completely the folders
forum_threads_list_panel and
forum_threads_panel from the
/infusions/ folder
5. Remove the following files from the
/includes/search/ folder:
search_forums_include.php and
search_forums_include_button.php6. Finally, preview the following code in a custom page:
WARNING! This will erase the forums! Don't execute it unless you really want to remove it.<?php
dbquery("DROP TABLE IF EXISTS ".DB_PREFIX."forum_attachments");
dbquery("DROP TABLE IF EXISTS ".DB_PREFIX."forum_ranks");
dbquery("DROP TABLE IF EXISTS ".DB_PREFIX."forum_poll_options");
dbquery("DROP TABLE IF EXISTS ".DB_PREFIX."forum_poll_voters");
dbquery("DROP TABLE IF EXISTS ".DB_PREFIX."forum_polls");
dbquery("DROP TABLE IF EXISTS ".DB_PREFIX."forums");
dbquery("DROP TABLE IF EXISTS ".DB_PREFIX."posts");
dbquery("DROP TABLE IF EXISTS ".DB_PREFIX."threads");
dbquery("DROP TABLE IF EXISTS ".DB_PREFIX."thread_notify");
dbquery("DELETE FROM ".DB_PREFIX."admin WHERE admin_rights IN('F', 'S3', 'FR')");
?>
WARNING! This will erase the forums! Don't execute it unless you really want to remove it.Note: The warnings are for people who might want to try the script, not for you. I just don't want anyone to come back and roar. :P
OK, if you want more details about removing certain stuff, just ask.
