+    Un PAD è uno strumento di scrittura collaborativa per scrivere testi, comunicati o quello che vuoi assieme ad altre persone.
     Questo è uno dei servizi di cisti.org, fuori dalle logiche del profitto e del capitalismo, dietro ci sono un gruppo di persone volontarie che si responsabilizzano a mantenere in piedi tutto questo.
 
     ALCUNE COSE DA SAPERE:
     - Per iniziare cancella tutto questo testo e inizia a scrivere!
     - Ogni pad può essere modificato da CHIUNQUE sia in possesso del sito (URL) o che possa indovinarlo facilmente, quindi scegli bene il nome del pad che vuoi creare!
-    - Questo pad verrà eliminato automaticamente dopo 60 giorni di inattività
-    - Una volta cancellato un pad NON ci sono modi di recuperarlo!
