Can I host a webinar, a live challenge or a course in Votel instead of Zoom?

For anything live, use Votel's meeting rooms. They are the same platform the 5 Day Challenge runs on, and they work like a webinar for many uses. You can present slides, share your screen, talk live, and manage the crowd with host controls such as muting people, choosing whether they can unmute, lowering hands and locking the room. Give the room a fixed, memorable link such as meet/yourname. On the white label plan it is your own white label Zoom replacement on your domain.

Votel does not have a dedicated webinar feature with webinar specific functions, and there is no prerecorded (automated) webinar feature. A meeting room is a live session.

For something prerecorded, such as a course or class, use Classroom and the Communities feature, where courses, classes and communities live.
