Do I need a re:publica account to submit a proposal to the Call for Participation (CfP)?

Yes, you can only access the CfP form if you have a re:publica account. With this account you can also manage your speaker, artist or exhibitor profile and edit your CfP proposal until the CfP deadline. Creating an account is free and only takes a few minutes. Here is the link to create your account: https://re-publica.com/en/user/register
