[nabs-l] Requesting Help with iClicker

[Miso Kwak]

Hello,
One of my courses for this fall quarter will be utilizing iClicker as a 
means of checking attendance and recording answers for pop questions in 
class.
Has any one in this listserve any experience with this device?
I would like to know how accessible this is.
Also, in case the device is not fully accessible, what accomodation 
could I request?
Please help me out.
Thank you in advance.
Miso Kwak
