futureme.org - write an email that will be sent to you in a year, or.

takenote.com.au - write a note that will be handwritten and sent to any specified address in Australia or to a stranger. if you live in Au can also give your address and receive a note from a stranger. I wrote one to a stranger "a note a note my kingdom for a note" (just playing to see what the site was, and I did enjoy typing and seeing the letters written by a pencil on a notepad) before I understood that these actually get mailed. that is cool. this site is "via Staedtler" - a paper company? - so I suppose the free service is offered for the benefit of the advertising.

on both of these, can browse gallery of notes others have written, if they elected to make them public. reminds me of
notguilty.com though there the browsing by strangers is the point. (what you write goes nowhere else.)

what is the category to which these sites commonly belong?
~ confessions, writings sent out like messages in bottles, ~eh. like postsecret.com also.
