@Biz..I'm looking into it, and will let you know soon. Sorry for being mistaken.
EDIT: I checked their forum, dear. And this is what I found:
Q: How do I get my dragons into my post/signature?
A: Click on your account, then click 'Get Code' for that dragon. Then you can pick your code from 4 different types, HTML, Neopets code, BBCode, and BBCode with TinyURL. Your best bet to use on forums is the regular BBCode one. Take that code then you go to your signature editor. Paste your code in there, and your eggs/hatchlings/adults will appear in your signature! You are not allowed to post your dragons on this forum because it encourages "egg spam"
