I came across this really useful site when a friend used it to collect people’s menu choices for his birthday party. It looks great for finding good times to meet with people by giving a range of options and letting people show those they can meet. It can also be used for polls. The replies are collated into a table and an alert sent that a reply has been made. There’s even an opportunity to leave comments.
The basic version is free and there is an option to go ad-free in the premium edition.
It is so easy to use I can imagine my student using it to conduct quick surveys as well as it being great for me.
