Hey Dan, thanks for the report on this. What have you done differently between the instructions outlined in the readme file and your actual site? Is it possible this is a theme or plugin conflict that you could check on a default 2011 plugin-free install?
It also might be worth talking to Tim, who wrote the initial tutorial, or checking the comments on his walkthrough at Creative Slice. While we’ve been able to find a way to lightly support it on our end…the code itself is all his. (Though, we are working on a frontend event submission plugin of our own for early next year).
