I'm working on Eve's registration papers. Our herd tattoo assigned to us is "XMAS". I understand that the letter for the year 2010 is "A". What do we tattoo? In one ear, do we simply put "XMAS" and then in the other ear an "A" and a number (such as 001) that we choose? Or does the ADGA assign the registration number that will coincide with the tattoo number? I guess I'm a little confused, looking at Snow's registration papers aren't really helping me and I'm trying to get this done. Any help would be great.
