Stamp Smarter membership is required to participate in any of the Community projects. With a membership, you can access and view the project databases; you can also add new "Online Listing Reviews" and add "New 20th Century Fancy Cancels". If you are interested in any of the other Community projects, additional permissions can be established. There are permission levels that allow you to add, edit and manage the existing data. Memberships are free and your information is kept private; no information is ever sold or used on any mailing list.
