The only thing you really need to think about is how people will access the sign up list. In the end, I selected "Public Anonymous" for my test so that people wouldn't have to create an account with SignUp Genius in order to sign up for my event. However, the advantage of having an account is getting a reminder a couple days in advance of the event.
If you want, visit the test site I made for parent conferences. You can even sign up if you want.
What do you think? Try using this the next time you want students to sign up for in-class presentations or to help organize your club's next event. I think it shows promise and I encourage you to share how you imagine it could make your job a little easier.
Happy Thursday!
