Your MarkUp and Ceros user accounts work seamlessly together!
If you are already a Ceros Studio user, simply use the same email address to create a MarkUp account as you use for your Ceros Studio account.
When you do, you'll be prompted to link you accounts together. To do this, enter your full name and then enter the same password you use for your Ceros Studio account into the MarkUp password field and you'll be good to go!
