[Michlib-l] Program Registration - Requiring a library card to sign up

Hello Library World! We are considering requiring individual to have a library card to be able to sign up for pre-registered programs. Programs that would have limited spots such as crafts, Minecraft (we provide computers), parties, etc. Our questions are: Who has implemented this and why? How do you implement this? Especially if you have online registration. Have you noticed any feedback about this from patrons? Thank you!
