Altru currently does not allow us to mark guests of Hosts as Will Not Attend on special events. You can change the guest's name to Unnamed guest or to another patron. Alternatively, you can mark the guest as No-Show.

Marking the guest as No-Show does not mark them as Will not attend, so if you want to return these seats to capacity, you could edit the event and increase your capacity.

If you would like to see this become a feature in Altru, please vote on this Idea in the Community. We encourage you to vote on this post as this is an opportunity to have a voice in the product development process. Our Product Management team uses a variety of methods to determine new features in Altru, and the ideas in the Community is one way they do this, so your vote helps Product Management prioritize the new features that we put into the product.
