I am using the Signup module with Calendar. The collapsible text that allows visitors to sign up for an event reads, "Sign up for Event Name". I'm not using this module to allow visitors to sign up for events but rather to get reminders about them. I'd therefore like to know how to change the "sign up" text to something different. I used the string override module to change what I could but this pretty much just affected the submit button text. Is there any way that I can accomplish what I want without having to hack away at the code?
