I love Kahoot, but I wish I could set a Kahoot to be open all year.  I would love to have them all posted on my google classroom for students to play and play again for vocabulary review.  Then I can pull up one at any time and play live so that we are reviewing together.  I feel like the students would be practicing their vocabulary all the time, all year to get ready for the impromptu kahoot sessions.  Please add this feature.  I don't like how the kahoots expire.  That is a lot of work for the teacher to reset every month, especially when you teach 6 different classes.  We should be able to set them to practice mode so that the students can get on there 100 times if they want until they learn the content.
