Works in all my tests. Does not capture protocol. |

This does not work at all. Very few of the regular expressions on this site do.

I understand. Thanks. I appreciate the help. :)
It includes all TLDs but how do I exclude certain matches?
I've noticed that if a jpeg image is listed in the text it matches the .jp part of the extension and thinks it's a URL.

You still have {1} there. It DOES NOTHING WASTE THREE CHARACTERS OF YOUR REGEX.
Get it? {1} is useless. Pointless. Always.
a matches 1 a
a{1} matches 1 a
Same exact thing
Get it?

Thanks for the suggestion about the PERL "URI::Find".
I'm new to regexps and this worked in my tests.
I didn't see a regexp on this site that did exactly what I wanted. I did notice the error with the second {1} after I'd already posted this. The last part of the regexp should be "coop){1}[:/]?.*?)(\s|$)" would also remove the need for the regexp to be followed by a newline or space.
Is there a way to change my post?

First off, the {1} do absolutely nothing except take up three characters (twice!). Second, this is case sensitive. Third, you should probably look at the Perl "URI::Find" module to see how to do it right.
