Online Fillout Forms Testing for Tournament

Click Here for the fillout form.
No, this is not real yet. Just testing.
If you have time to kill like I do, please try and see if it works.
And give back suggestions or changes I should make.

One big issue I can think right at the spot is that I made it to accept one form per IP.
Very good against people who spam register for fun, but this will cause inconvenience for
those households with brothers/sisters/roommates who wants to try the tournament too (if they're using same internet).

Also testing this sign-up: http://challonge.com/tournament/signup/hiyuymqj
this will make things much more easier, but no idea what the sign up form is like. i can't test it for some reason...

Thanks,
