Works in 3.8.2
One exception for installation.

in MEMBERINFO you need to look

<if condition="can_moderate()">
<li class="thead"><a href="moderator.php?$session[sessionurl]do=useroptions&amp;u=$userinfo[userid]">$vbphrase[edit_user_profile]</a></li>
</if>

And add after

<!-- Hack: Username Management (MarcoH64) -->
<if condition="$mh_unm_can_change_other_name">
<li class="thead"><a href="$mh_unm_modcp_link">$vbphrase[mh_unm_change_username]</a></li>
</if>
<!-- / Hack: Username Management (MarcoH64) -->

The rest as it is written in instruction in original.
