[Plugin: Automatic Newsletter] Maybe a incompatibility with the search?

Hi,

After having installed your extension, when subscribing a name/email and pressing the “subscribe” button, we arrive at a page which says something like: “Sorry, the page you are searching cannot be found”. Looking at the code, and seeing that both the search field and this plug-in uses the same address for the form action, I arrive to the conclusion that when we press the “subscribe” button, the form content is gotten by the Search function of WordPress. Of course, nothing works as these were not the expected fields…
