It would really nice to be able to invite guest collaborators for bases that you didn’t need to pay for. I like the Slack model where every member has 5 free guests to add in one channel.
Maybe you could do the same so that every paying workspace collaborator has 5 guests to invite. The guest could only have access to one base and if gain access to more than one they would be billed for.
Rigth now when you have to collaborate with people outside your team you have to move a base to a free workspace. And can understand why Airtable choose to do this but maybe guest access could be a way in between.
