The Pennsic Registration Office is now accepting registrations for Pennsic 45, to be held July 29 through August 14.
The registration web site's security system has been changed, and now anyone using the electronic registration system needs to create a new login for this year. Quoting from the login page:
Everyone must create a new account for Pennsic 45. Many of you had multiple accounts which got confusing when you tried to find the account tied to your paid registration. Many of the really old accounts didn't satisfy our new security requirements so we're fixing that as well. Going forward you will login with your email which will make resetting your password easier and you won't have to remember a username.
