No. Neither the question asker nor the answerers need to be logged into the CALI website. This means you can use InstaPoll with guest speakers who aren't CALI members or in situations, such as conference presentations, that have non-CALI members in attendance. It also means that if a student has forgotten their CALI login information, this won't delay the polling process. Basically, you can use InstaPoll anywhere there is a web connection!
