Your entry will be identified by your anniversary greeting. (Ex) Player ID 123456 Unit Of Choice Burny Type Anima Anniversary Greeting I Love Bf! Email Someguy@gmail.com

If I were to check if my form was submitted, I'd go back to this wiki page and click the link to choose a free unit. If it says "I Love Bf!", then I know it got submitted, if it didn't, I'd have to re-enter the form. Did that answer your question? Hope it helps ;)
