Please remember that to keep all the opportunities monitored and clean for all participants, there are limits on how many challenges you can have open at the same time.
As a Lite member, you can have 1 open challenge at a time.
As a Premium member, you can have 2 open challenges at a time.
As a Pro member, you can have 3 open challenges at a time.
If you are a new ViewBug participant and still under a Premium Trial period, you must wait for the trial to finish to create a challenge (help us keep it fair for all).
