It will be great if you told him how to remove it instead of saying where at.

Go to Style Manager>Skin Name>Edit Template>Postbit Template>Postbit(Double Click it)

Find

<if condition="$post['joindate']"><div>$vbphrase[join_date]: $post[joindate]</div></if>

<if condition="$post['usertitle']"><div class="smallfont">$post[usertitle]</div></if>

Than go to Postbit Legacy and find

<div align="center"><if condition="$post['usertitle']"></if></div>
			<if condition="$post['usertitle']"><div class="smallfont">
			  <div align="center">$post[usertitle]</div>
			</div></if>

<if condition="$post['joindate']"><div>$vbphrase[join_date]: $post[joindate]</div></if>

Just delete those codes.
Hope that helps.
