Do I need a Unissu account to sign up to the event platform?

Two platforms; one account

Yes!

The event platform has been created by Unissu, so whether you sign up via the event platform or Unissu, you will end up with a Unissu account.

If you sign up to the event you will automatically be given a Unissu account via the sign-up process.

If you already have a Unissu account, you can simply sign into the event platform using your Unissu details.
