Not sure I'm following the logic here. You're getting multiple entries because people (like me) are making multiple entries. I've logged in three different ways, and it still bounces me to a "you're not logged in" page. The ticket count goes up one each time I do it though lol.
I logged in on the home page. I logged in on the entry. I logged in when I went to see the tickets and it wanted a log in there. On the ticket log in, it wanted an email and not a user name. Reminds me of my bank, I have to call them every time I try to go there (not often so I forget) because they say user name but what they want is account number or whatever.
You have a chance to win a great PV... it's probably worth the hassle.
