SignUp Genius is a free and easy way to create and organize online sign-up forms for all kinds of group activities. SignUp Genius creates a simple webpage on which people can sign-up for activities that you’ve specified.

You can make your sign-up sheet public or private. Once you’ve created your sign-up list visitors to your list can sign-up for the activities you’ve specified. You can monitor the sign-up list as it is filled and visitors can quickly see which slots are already taken. SignUp Genius provides a myriad of themes and styles for your sign-up sheets. The image below is a screen capture of the sample field trip sign-up sheet that I created on SignUp Genius.

Applications for Education
If you’ve ever held a classroom party and ended up with twelve trays of cookies but only two bottles of juice, you know the value of having a well-organized sign-up sheet. With SignUp Genius you can avoid that. Need chaperones for a field trip? Post a list on SignUp Genius. You can share your SignUp Genius lists by giving out the url or emailing private invites to parents (SignUp Genius supports mailing lists).
