Sometimes you need the opportunity to leave some notes for yourself.
I use MS Outlook. But Outlook is not always with me. And I can not see what I wrote in the Outlook notes when I have access to the Internet and the site habra-cadabra.
I suggest giving the opportunity to create notes for yourself on the site, for this you can use the ready-made tool - Habrapmail. It is only necessary to allow the person to send letters to himself, in addition to the list of recipients.
