reReplace(str, "@([a-zA-Z0-9]{1,16})", "@<a href='test'>\1</a> ", "all")
change 16 to the max length of your usernames. I'm just assuming you have a
max length since you started to specify 1 through something but didn't
finish... you just have {1,}

Subject: Wierd regex problem (isn't it always)
Hi
I'm trying to do a look through as string to find usernames and add
<a> tags around them ala Twitter.
The regex I think is fine but when I use reReplace 's back reference
I'm not getting the result I thought I would of. Heres the code. Can
anyone see anything obvious?
Cheers, Andy
<!--- String to be manipulated --->
<cfset str = "First username is @andrew and second is @jarrett" />
<cfoutput><p>#str#</p></cfoutput>
<!--- The Regex
(@){1} - First back reference is the @ sign. Look for one of these
([a-zA-Z0-9]){1,} - Second back reference is the username
--->
<cfset reg = "(@){1}([a-zA-Z0-9]){1,}" />
<!--- Using reReplace we take the second back reference and wrap
an <a> tag around it --->
<cfset usernamePos = reReplace(str, reg, "@<a href='test'>\2</a>", "all") >
<cfoutput>#usernamePos#</cfoutput>
