Backreferencing a single, static character is silly. It just wastes
memory and processor time. You're throwing it away, anyway.
{1} is useless. It means one of. Which would just be the thing by
itself.

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,

Try something like:
rereplace(string, (.*)\(.*?\), \1);
Not tested, YMMV, and probably not very efficient. I'd probably look
into more conventional string manipulation to take care of it. Like by
finding all the open parens, and nixing everything from the last one on.

Regex is frequently more compact. Regex is rarely faster if there's a
fairly simple way to do it using standard string manipulation. As much
as I love regex, I'll use a couple of standard string manipulation
functions instead if possible.

Good call. Better than mine. I don't think you need the parens
wrapping the literal parens, though.
