1) Upload plugin to plugins/forummodkit
2) Run "sql.sql" file from folder "sql" in phpMyAdmin
3) Install plugin from Administration panel
4) Edit plugin settings in Administration panel
5) Set rights to this plugin. Read access for all users. Write access for moderators that can do warnings. Admin access for group that can ban.
6) Add tag {HEADER_MODKIT} in header.tpl near link to Administration panel
7) Open system/header.php and move:

-------------------
/* === Hook === */
$extp = sed_getextplugins('header.tags');
if (is_array($extp))
	{ foreach($extp as $k => $pl) { include('plugins/'.$pl['pl_code'].'/'.$pl['pl_file'].'.php'); } }
/* ===== */
-------------------

from down to up before:

-------------------
$t = new XTemplate($mskin);
-------------------

Must be:

-------------------
$t = new XTemplate($mskin);

/* === Hook === */
$extp = sed_getextplugins('header.tags');
if (is_array($extp))
	{ foreach($extp as $k => $pl) { include('plugins/'.$pl['pl_code'].'/'.$pl['pl_file'].'.php'); } }
/* ===== */
-------------------

Without this step tag {HEADER_MODKIT} dont work...

8) Add tag {USERS_DETAILS_WARNS} in users.details.tpl
9) Add "Warnings: {FORUMS_POSTS_ROW_MODKITWARNINGS} {FORUMS_POSTS_ROW_MODKITADDWARNING}" in forums.posts.tpl near user info fields, like age, posts, website, etc...
