A webinar is a virtual event typically hosted by organizations or companies and is broadcasted to a selected audience or a group of people who voluntarily choose to be there. Webinars are one of the key ways to nurture engagement in a community but you have to ensure that webinars create a necessity for people to join and participate. Webinars must have exponential value in order for people to keep coming back to it.
A roundtable or a community roundtable is an interactive session for all community members to join and discuss almost anything.
