I appreciate your plugin, I would make it work on every author.php so that a visitor on the site who clicks on the author's name of a post could send a message to the author.
I don't if I'm very clear - take a look on this the message should be sent to Stéphane Bikialo and not to me.
I tried several things, but most answers I found related to forms on posts.
I think I have to do some short code supplement to the author template, but what?
Any hint appreciated
