The LetterMag Post seemed to have a lot of feedback. Generally, people have been searching the web to find previous issues and any information about this penpal magazine, but encountered two problems: either there wasn't any working links or the links that they discovered were only in German.
I will try to bring things to prospective (as far as I know them). By the time that the LetterMag was released, Deutsche Post (German Post Service) had undertaken this project to keep the art of penpalling and correspondence alive. You could sign up with email, but the correspondence was strictly snail mail. It was a win-win situation for both Deutsche Post who marked increase in the use of their service and of course for all of the penpals who got to have a free and totally new paper magazine, called LetterMag.
Letternet is advertised as the world's largest penpal club.When you "arrive" at their website you can look through their news and updates. However, for all of the features to become available to you, you will need to register.You fill out their application and in a couple of days you will receive the activation code in your snail mail. You can read in the FAQ questions that "Letternet is both an online magazine and a network of pen pals, so Lettermag was discontinued when Letternet was created.".
And there you have it - the connection between Letternet, Lettermag and Deutsche Post and why the search engines are giving the same search results. I will try to get a hold of the new online magazine of Letternet and I will be back with a review real soon!
