Andy,
I'm not a regex ninja, like some, but I think what you're looking for
is this. Escape the space character (using ^) so that any
backreferences stop at the space character.
<cfset reg = "@([a-zA-Z0-9][^ ]+)" />
Then you can use the first backreference:
<cfset usernamePos = reReplace(str, reg, "@<a href='test'>\1</a>",
"all") >
HTH,
Jon
