|  *   permission change has been made by the sender which affects the target channel. The hub controlling
 | |

 | |
|  *   channel). These are decoded here, and if necessary and abook structure (addressbook) is created to store
 | |
|  *   the permissions assigned to this channel. 
 | |
|  *   
 | |
|  *   Initially these abook structures are created with a 'pending' flag, so that no reverse permissions are 
 | |
|  *   implied until this is approved by the owner channel. A channel can also auto-populate permissions in 
 | |
|  *   return and send back a refresh packet of its own. This is used by forum and group communication channels
