Stamps Unlimited accepts all members, just click on the "join" button and you automatically join the fun.
There are a few gallery folders to submit stamp art to:
All Stamps 12 & 13 - All stamps get submitted to these folders regardless of theme, size, shape, etc and all submissions are automatically accepted.
Stamp Templates - All stamp templates and bases get submitted to this folder and all submissions are automatically accepted. Members should feel free to browse this gallery folder and use some of the wonderful templates to make stamps.
NOTE : The All Stamps 1-11 galleries are full and nothing can be submitted anymore (thanks for all of your support in submitting stamp art).
