In Celtx, a 'Paid Collaborator' is a user whose subscription is paid for by another user. Collaborator 'seats' can be added and removed from your subscription at any time.
Note: if you are a Professional or Enterprise Account holder, please speak with your Account Specialist about your Paid Collaborator options.
Collaborator Discount, Price, and Subscription Type
Collaborators you add to your account are done so at a 50% off collaborator discount – relative to to the price of the primary subscriber.
The cost of adding a collaborator is calculated at a prorated rate depending on your Billing Cycle. So, for example, if you add a collaborator at the six-month mark of your annual subscription, their cost will be 50% of your subscription (because of the collaborator discount) at 50% of your annual rate (because you are already six-months through your annual subscription).
When you add a collaborator, they receive the same subscription-type as you. If you upgrade your subscription, this too will apply to any paid collaborator seats on you account.
Add a Paid Collaborator
Before you can add a collaborator, they must be Shared on at least one project within your Studio that you "own" (i.e. that you've created).
Any users who are shared on one of your owned projects can be added as a collaborator via the "Plans" page, under "Management". Simply click "Add" next to their name, and confirm the subscription update.
If you are currently a trial user, you can select your collaborators once you've selected your plan and before confirming your payment.
Remove a Paid Collaborator
Note that "Unsharing" collaborators from all your projects does not remove them as a paid collaborator.
To remove a collaborator from your subscription, click "Management" and then "Plan". You will see all the paid collaborators on your subscription here. To remove a paid collaborator, click the 'Added' button; the same one used when adding them to your subscription. Then confirm your selection. They will be immediately removed from your subscription.
If you would also like to remove them from your Projects, consult the article on Sharing and Permissions.
