For the 100 participant limit - is that how many can be in at the same time?  Or, it is whoever enters at any time (example - if someone logs in posts a Q and exits, that’s #1. Then another user logs in later that’s #2).

Hi @jamierefresco

The limit refers to the overall number of participants that join the event no matter if they ask a question or vote in polls. That means if one person joins and then leaves the event, they’re counted as one participant, then another person joins, they’re counted, too etc. 

Hope that makes sense.

What happens to the people who try to log in after the max is reached? do they get a message?

Hi @DrK,

Participants who join after reaching the limit will not get a message, but it will show up in the participant count in your event analytics. They will be allowed to join the event and participate in polls and Q&A.

However, if you exceed the participant limit significantly (i.e. 10% more than the participant limit), we might block the event.

Hope this helps! Let me know if you have any further questions :)
