Murry's solution here is ideal since it only captures the single occurrence.
Since I want to use it for a preg_replace(), it is perfect.
A couple of folks sent this pattern [^@]@[^@]; but, it doesn't work because I
then have to remove the unwanted caracters on either side.
All it says is [not @]@[not@] but, it captures the 2 characters on each side.
Murry's solution (?<!@)@(?!@) is good since it only captures the "@"
Thanks everyone....
