survey gets 250 responses in a day

The survey to find people's perceptions of 4 specific imprecise regions went live yesterday to all student and staff at uni. It has already got over 250 completed responses. Great! I will have to upgrade my survey gizmo account in order to be able to read them all, but I will not do that until I know whether I need to view 1000 or 5000, which are different options at different costs per month. I seem to have created a survey that interests people anyway.
