Now why no you ask well I will tell you. In order to have Messenger change the way it communicates to the server when telling it the status you will be signing in as would involve changing the internal code in Messenger, now this is illegal and in order for Messenger Plus! to stay legal and around it cannot do such things. Messenger Discovery gets around this by acting as a Proxy communicating with the Messenger server and the application and changing the status sent to the server to appear offline. And Patchou wont use Messenger Plus! as a proxy so... unfortunatly its either Messenger Discovery or JRNZLoader which is used for Polygamy and any status you want to sign in as. For that application just search
