I'd love to use your plugin but it doesn't seem to be working for me. Any link I put in remains an ordinary link.
I'm working on a rather fresh install of WordPress and deactivated the 3 other plugins I was using to see if any of them would be colliding with yours. That didn't seem to do anything.
I've double check and yes, the pluging IS activated (hehe).
I'm kind of lost here and I hope you will be able to provide me with a solution (as soon as we find the cause of the problem, that is).
