Just add this in your postbit template
HTML Code:
<if condition="$post[usergroupid]==X">
HTML GOES HERE
</if>
Change X to the usergroup id. And you can do something like this.
HTML Code:
<!-- Admin Title -->
<if condition="$post[usergroupid]==6">
HTML GOES HERE
</if>
<!-- /Admin Title -->
<!-- S.Mod Title -->
<if condition="$post[usergroupid]==5">
HTML GOES HERE
</if>
<!-- /S.Mod Title -->
<!-- Mod Title -->
<if condition="$post[usergroupid]==7">
HTML GOES HERE
</if>
<!-- /Mod Title -->
<!-- Member Title -->
<if condition="$post[usergroupid]==1">
HTML GOES HERE
</if>
<!-- /Mmeber Title -->
See the pattern?
