(No you have to email the people or admin of PIMD and ask to be unsilenced or delete the app and reinstall it. )
(Yes. I shall just follow me and wall me so I can quickly enable join requests. But be quick Henry!!! We'll miss ya! Specially Lucy oh how will she go on! )
(Deleting and re-installing the App will not get you UNSILENCED. You can't reset either. You can email.)
