Thank you, I assumed that was the syntax; but wasn't positive.
my guess would have been:
<if condition="$bbuserinfo['usergroupid'] != X"> Show Stuff here r</if>
But I like the assurance
btw - you don't need the single quotes around the usergroupid?
also is this proper?:
<if condition="($bbuserinfo[usergroupid] != X) or ($bbuserinfo[usergroupid] != Y)"> Show Stuff here r</if>"> Show Stuff here r</if>
