Here's the solution I came up with... thanks for everyone's
help. Maybe this should be a UDF :)
<cfset CurrentlyActiveUsers = "a,b,c,d,e">
<cfset ExistingUsers = "b,d">
<cfoutput>
<cfset newlist = CurrentlyActiveUsers>
<cfloop list="#CurrentlyActiveUsers#" index="x" delimiters=",">
<cfif ListContains(ExistingUsers, x, ",")>
<cfset newlist = ListDeleteAt(newlist,
ListFindNoCase(newlist, x, ","), ",")>
</cfif>
</cfloop>
CurrentlyActiveUsers: #CurrentlyActiveUsers#<br>
ExistingUsers: #ExistingUsers#<br><br>
Cleaned List: #newlist#<br>
</cfoutput>

Correct me if I'm wrong but that doesn't do what I'm asking.
I want to remove all items in ListVar1 that appear in ListVar2.
They are not already duplicated in ListVar1.
