Usergroup Condition

[Mastar]

How do I write a condition for a group?

If a user is in admin group or supermod group show this.

<vb:if condition="$groupid['1']">

??

--------------- Added [DATE]1296179691[/DATE] at [TIME]1296179691[/TIME] ---------------

or Using usergroup conditions
<vb:if condition="$usergroupid['1']">

--------------- Added [DATE]1296181351[/DATE] at [TIME]1296181351[/TIME] ---------------

I tried:
<vb:if condition="is_member_of($bbuserinfo, 5,6)">
and
<vb:if condition="$bbuserinfo['usergroupid'] == 6">
but nothing
