Some members may want to sign up for events using their iphones instead of desktop or laptop computers.  The event signup process has 4 screens which require user input.  At the bottom of the first screen, you must hit the "Register" button.  The second screen then asks for an email address and has the annoying "are you a robot" test, unless you are already logged in. At the bottom right of the second screen you have to hit "Next".  The third screen asks for guest registration information, and you again have to hit "Next" at the bottom right.  The fourth screen is the "Review and Confirm" screen, and to complete the registration you have to hit "Confirm" at the lower right. On desktops and ipads, the "Next" button on the third screen cannot be seen unless you scroll down.  On iphones, the "Next" buttons on the second and third screens can only been seen if you scroll down.  If you don't get to the "Review and Confirm" screen, and hit "Confirm", your registration will not be recognized by the system. 

If you do not receive a confirmation email, you did not successfully register.  If you are not sure if your registration is complete, you can click on the event on the home page of the site, and then click on "nn registered", (where nn is the number registered), and you can review the list of those registered to see if your registration was completed.

Attached are iphone screen shots for the third screen (first 3 images) and the fourth screen (last image) of the registration process.
