What is ActivInspire?I have activotes but the hub is missing. Do I need this?

Hi Anne 

How have you registered the devices if you don’t have a Hub?  Are these the first generation ActiVotes and have you registered them to your 2nd Generation ActivBoard? 
Have a look at this article on our Knowledge Base here for more details. If you registered the votes to your board, then you don’t need a Hub.
