To sign up for LPU scroll halfway down the main page. You have two options to choose from. The annual pass or monthly pass. The monthly pass gives you access to the LPU chat and LPU/LPTV videos and episodes. Annual pass gives you access to those features plus the ability to purchase tickets early, chance for meet and greets and more.
If you have already purchased an account and are having trouble getting access please send either I or Dragonlp20 for assistance.
