 ## Valid event names
 
 We want to keep events very simple. That's why we only allow alphanumeric characters and underscores (`_`). We convert events to lower case and invalid names to a version which is valid. This way your events are always saved. If you return a function for an event we run this function and if the result is a string we will store the event. For example: `sa_event(function() { return "clicked_signup_on_" + window.document.location.pathname })`.
