Ey this is first action I make. Using this you can play around with a basic stamp and customize it according to your wishes. I also include a .PSD file with a few examples and a PNG file which contains the borders of the stamp. Just unzip the file and open the INSTRUCTIONS.txt. Hope it helps you to go deeper with photoshop. Anyway, have fun! Cheers!
P.S: This action has only been tested with CS3
