If an invited user does not have a DSX account, the user receives an email invitation to create a DSX account. When the user creates a DSX account, the user can see your project and the user's status on your collaborators list changes from Invited to Active.
Incorrect -- DSX will not let you invite a user if there is no matching DSX account
Hi there! Thanks for reporting this - we've pushed a fix in production where an invitation to DSX is sent to invited collaborators who don't have a DSX account already. Once the invitee presses on that invitation, they are brought to the project that the original inviter added them as a collaborator for.
Before users would receive an error message if they tried to invite someone who didn't have a DSX account.
