In your "Additional CSS Definitions", add this code in the 2nd box....

.rm_userinfo {
border: 1px solid #9FB2B8;
margin: 3px;
padding: 3px;
background-color: #DDECF1;
border-top: 1px solid #000;
border-right: 1px solid #000;
border-left: 1px solid #000;
border-bottom: 1px solid #000;
}

Customize the colors to your liking.

Then in the postbit legacy template (Using the "Join Date" as an example) find....

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

And replace with

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

And just pretty much do that for all the fields you want to look cleaner
