Nonprofit PR

This semester I will be working my practicum for Digital Bridges Milledgeville. All last semester I worked for them as their Public Relations student worker. Over the summer, one of the management figures changed, thus, my job description has changed. I used to find articles online 2 days per week which pertained to how technology could be related to and/or affect the community. A huge project which I am beginning my work on is working with a website called ten questions (10questions.com). It gives people a change to record themselves asking questions which they would like to ask to the candidates for governor and house, both at local and state levels. Visitors of the website are asked to vote on the questions which they would most like to be answered by the candidates. The ten questions with the most votes will be asked to them. My job is to create a campaign to draw people into Digital Bridges in order to record their questions. Any ideas?
