This means you're still using the sample version of Keep&Share’s “Self-Book” feature, which has a limited version of the full features, including Group Event signups are fixed at a 100-person capacity. (The sample version also doesn't have the option to create your own custom Self-Book Forms, and your calendar is limited to 20 sign ups a month).
If you need any of those features, upgrade to the full “Self-Book” subscription and you will be able to control your event capacity, plus gain access to the wide range of customization features available with a subscription.
Note: The Self-Book subscription is only available to paid accounts. However, during the free trial period of a Keep&Share account, you can preview the features of a full “Self-Book” subscription. To keep access to those elite features though, when your free trial ends you should upgrade to a Solo or Team plan and also sign up for the optional “Self-Book” subscription.
If you currently have a free Basic account, you can try a 15-day free trial of our Solo plan to try out all of our premium features.
