Usage
If the list begins with one or more empty entries, this function drops them, as well as the first
element.
ColdFusion ignores empty list elements; thus, the list "a,b,c,,,d" has four elements.

<cfquery name = "GetMessageUser" datasource = "cfdocexamples">
SELECT Username, Subject, Posted

<cfset temp = ValueList(GetMessageUser.Username)>
<p>Before editing the list, it is:&nbsp;
<cfoutput>#ValueList(GetMessageUser.Username)#</cfoutput>.
<p>(Users who posted more than once are listed more than once.)
<p>The first user in the list is:
<cfoutput>#ListFirst(temp)# </cfoutput>
<p>The rest of the list is:&nbsp;<cfoutput>#
ListRest(temp) #</cfoutput>.
<p>(Users who posted more than once are listed more than once.)
<p>The last user in the list is: <cfoutput>#ListLast(temp)#</cfoutput>
