[turba] manage contacts lists

[Andrea Zagli]

i'm sorry for this very stupid question, but i didn't find a way to  
manage contacts lists

i can create a contact list from a contacts selection and i find it on  
composing a new message

but:
- how can i delete a contact list?
- how can i remove a contact from a contact list without remove the  
contact from the address book?

thanks in advance
