Dear Mario, Jean-Philippe and others, Many thanks for your responses. These solutions are more or less what I came up with, too. However, one thing I didn't find out how to do so far is how to make the list of friends private, so that even other friends do not see it.
Did one of you manage to do that in an accessible way? Thanks! Sherab. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected] Archive: http://lists.debian.org/20130924160010.GA30730@pema
