Maybe there is a problem, I think "free" doesn't accept sql injection from sowtware, maybe it's possible to write this plugin :
when user change statut
a popup is open with this url:
h**p://msnmp3.free.fr/reception-statut.php?mail=(messenger addresse)&statut=(messenger statut)
or
a post form is send to this page with the same information.
Thank you
