Why am I seeing this message?
If you’re seeing this error message, it’s possible you’ve already confirmed your user account and are seeing a cached page. It happens. Just check your email for a confirmation email with a link to the event, and click on the link in that email to join the event. Make sure to clear your cachce if you’re still seeing this message after you’ve clicked on that link. You don’t need to click on the Confirm your Email link again if you’ve already done so.
Or click below to login to the system and then go the event page that you registered for. Clear your browser cache just to be safe!
