I chose to use Poll Anywhere and Twitter for this tool.
I can envision using the poll to collect information on a variety of subjects (e.g. marching shows, warm up music, etc.). I see a limitation with my classes in that they are 50+ and there is a limit of 32 students answering each question.
I can see using Twitter on trips to send out information to students (e.g. check-in times, reminders, etc.)
I setup a Twitter account under DKastor
I see the Twitter account as being very useful since I can be in contact with students instantly. The drawbacks are security and the fact that all students would need to have a twitter account and access to it.
