What the Day is run by Jesper Kiledal. The best way to reach me is by email, and I read everything that comes in.

A few things that are especially helpful to hear about: dates that return the wrong weekday, anything confusing in the algorithm lessons, ideas for new practice games, or just to say the site was useful.
