[turba] How do I share contacts in Turba?

[Luis Felipe Marzagao/Andamentos]

Hello,

I've successfully installed horde framework (3.1.4) and Turba (2.1.4) in 
my F7 box. I'm using MySQL as backend and everything seems to be working 
just fine. I can create entries in my contact list in Turba, as well as 
delete them.

But I just can't find any information or any option that allows me to 
share contacts between users. Can you give me a light here?! Somewhere 
to start from?!

The option 'use_shares' is set to => true in sources.php at /turba folder.

But I can't find ant way of sharing the contact lists.

Please, help?!

Thanks a lot!
Luis Felipe
