Josh or Cathal,
Could you explain a little bit more of what you need to do to make sure false web activity is not created for those tradeshow leads as a result of all the leads filling the form out on the same device?
Follow the Referral Form pattern -- there are many posts in the Community about it, and a blog post (you'll see links to it when you search).
Cathal's notes are not complete (turning off Munchkin on that single page is not enough) but it is still simple to roll out. Just follow the instrux on other threads. QA thoroughly.
