You can do either! But the Burnalong team recommends you start by going LIVE at a set day and time each week until you build a following, and then try Open Door LIVE once you know more users will be on during that LIVE time slot. All LIVE and OPEN DOOR LIVE classes should be saved on-demand. Users on OPEN DOOR LIVE will not be seen on the recorded classes once posted on-demand.
For details on how to partake in both types of classes, please check out How do I host both types of live classes? in the general partner FAQ.
