Unfortunately, you can't use activeCollab Hosted Demo in this way.
Paying a monthly fee for the demo extension would mean that we host and maintain activeCollab for you. The Hosted Demo platform is just here to introduce you to activeCollab and to demonstrate all of the features and capabilities of the product. It's here to help you make a final decision about whether you are going to opt for a full license or not.
Once you have tried activeCollab and evaluated it, you have to choose to buy a license or not. If you decide that activeCollab is not the tool for you, you can just walk away. The data from your hosted demo will be saved for another 30 days after your demo expires and may be exported if you wish (by using the appropriate link on your www.activeCollab.com profile page). On the other hand if you decide to purchase a license we can help you transfer your demo data to your new installation of activeCollab!
