We are hesitant to use the feature where NPOs can submit for approval volunteer events because once they are approved there is no option for the admin to edit. This IS a feature that is available to other volunteer events/projects. It would be very useful and assuring to have this ability because no one gets something right at the first try. Plus, there are features such as enabling tshirts, adding shifts etc that are not available to the NPO that should be available to the admin but don't seem to be for events created through the NPP.
And oftentimes it isn't very clear how a participant should officially sign up with that nonprofit. They can't just sign up on our side, they need to notify the nonprofit or complete a signup link.
