WordPress Events RSVP Plugin
I have released a wordpress plugin to schedule events
With this plugin you can have people sign-up for an event with a form on your website. Once people sign up they receive a confirmation email.
You can also set a maximum number of people for the event. When the event if full, the sign-up form disappears and people cannot sign-up anymore.
In the WordPress admin you see the list of people who signed up for the event. You can also cancel sign-up.
