Tagging "Probationary" users - mechanism to alert mods/admins to a user's probation?

[stardotstar]

OK so I have put this in the postbit:

<!-- Is Probationary? Start -->

<if condition="is_member_of($bbuserinfo, 6, 5) AND is_member_of($post, 136)"> 
<img src="images/P.gif" alt="User is on P-Plates" />
</if>

<!-- Is Probationary? End -->

This displays as a P plate graphic on postbit for members in the secondary "probation group" only to members of the admin or supermod groups.

So far so good.

Trying to work out how I could get the last usernote to display as the popup box alt text:

In searching I have found various references to components that apply to the usernotes.

$usernote[total]

($vbphrase[last_note]: $usernote[lastpostdate] <span class="time">$usernote[lastposttime]</span>)

But I am not sure what they can be used for, if they need more conditionals around them to display since the group test is already done and the groups in questions hould be able to see the notes...

Any ideas?
