Email Lists

Do you like trading postcards?
Do like discussing postcard topics?
Do you like participating in contests?
Do you like participating in group swaps?
Do you like participating in Round Robins?

If you answered "Yes" to any of these questions then I suggest you visit Yahoo Groups.
Yahoo Groups has hundreds of email lists that you can join and if you do a search for postcards, you will get quite a few to choose from.
I joined 18 different postcard email lists and am having a blast trading with so many people around the world.
