I.U.O.M.A

 More than 10 years ago, while looking for pen pals on the internet, I ran across one of Ruud Jansen's websites, the TAM Rubberstamp Archive. One of several sites that Ruud had on the web at the time. That site opened a door for me into a whole new world of postal delight... Mail art.
  It was through the archive site that I learned about I.U.O.M.A. The International Union Of Mail Artists is a brain child of Ruud Jansen, a native of the Netherlands and long time mail artist. He originally started the "Union" in 1988 as a joke, but it has grown into a virtual world where more than 2000 mail artists come to interact with other mail artists. There are forums, members can post scans of their sent and received mail, join various interest groups and can even have their own blog on the site. If you haven't ever visited the site, you should give it a peek, there is a lot going on there. It is a great way to meet mail artists from around the world.
