So here is my thought. 
Since there is [b][i]NO[/i][/b] form of clan communication in game, other than when you are in a fire-team, how about using the postmaster as a working[i] post office[/i]? 
The image is a graphic I created in order to show a mock-up of the idea.
If a clan member wanted to put out a message to the [b]ENTIRE [/b]clan, just a few members, or just those on your friends list, they could just ...
• go to the Postmaster
• create a message
• select the recipients from a list type
  <><><> • Friends List
  <><><> •  Clan Members
  <><><> •  or just choose [b]ALL[/b]
• select the appropriate icon for the topic of the discussion 
• and hit [b]SEND[/b]
• the postmaster delivers the message 
When the player/clan member comes to the tower and checks in with the Postmaster, they could review their message(s).
We are all aware how it is done now.
[b]Option 1)[/b]
• Go to the FORUMS area for your clan
• Create a post
• Pray the the members actually READ it
• Hope they respond
[b]Option 2)[/b]
• Try to contact them in game via fire team (extraordinarily difficult for a large clan)
• Beat head in to wall after being unable to reach more then 2-5 people at any given point in the day. 
• Repeat
Also ... the PS3 only allows for 100 in your friends list so using the built-in messaging system could be problematic. 
Here is why ...
• Say you are Praiano from Gran Turismo fame. (He does car tunes like nobody's business. )
• Because of that, his friends list is maxed. 
• Now, say he buys Destiny and joins a clan. 
• He can not use his PS3 message system to contact them because his friends list is full of GT players. 
• That is why it needs to be in-game. 
Guardians ... what say you!?
