How do I know what events I'm signed up for?
Two ways - you will receive an email message for each event you sign up for. Second, you can click on the top tab item "Play!", and then click "My Events". You will see just about everything the system is keeping track of, including which events you're signed up for. Note that some of the information on that page is a bit extraneous, but for the price we pay for this software (open source = free!) we're willing to overlook some of that.
