I know I dont read the PDA ...I tried but as many have said you get lost real fast.
How about the PDA section you still have your main diary but you are also allowed to start a I hate to say it this way but, " granny died" then after a month it can be deleted. Or I found out I have ms...maybe that one can stay since it is a life long illness and many have "been there done that" and others learn from reading it even if its a year old.
That way its not adding more sections just allowing "bad news" to get to everyone with out the hunt and peck.....
