Rich,
GOOD JOB!!! The next thing you might want to consider is to have the username and password filled in for your users. This will work if they are registered users, have cookies enabled, and set. This way they won't have to enter all that info and they can just vote. If they are not registered, or don't have a cookie, the fields stay blank. LMK if you need help with this...but it isn't hard (shoot, I DID it LOL). Congrats!!
