Need input!

I've been thinking about having a contest on the blog to guess the gender and date of birth for our baby.

Here's where I need your input:
1) Are there any other things you want to guess about...weight and height?
2) Does anyone have a suggestion for a good website to host the contest? I've seen these online contests before, but I didn't save the link and I'm sure that there's more than one.

Of course I will give you my due date and other fun stuff like the symptoms of this pregnancy and how they compare to the symptoms I had during Lukas and Natalie's pregnancies...just to help you make an educated guess.

Let me know if you have any other suggestions so I can come up with a good contest from the start!
