Under your username, you'll see that it says "egg"
This is your ranking. It doesn't really stand for anything, other then your post count.
If you're quite active and post a lot. Than you'll one day see that it will change to "Chick" The more you post, the more your ranking will change.
It's just a fun way of keeping track of your posts.

Well, any questions, feel free to ask.

Thanks.
