it's pretty much like what slappy posted, except I don't have an extra space after the groupid # like he does:
Code:
<if condition="$post[usergroupid]==X ">
When I get home I'll post my code. If you want to see it in action, got to the house of help (in sig), go to off topic forum near the top. You'll see a test thread there. I believe I still have the code active (can't see site from work).
