Use the 'My Details' button in the menu to review the records of your present details. An 'edit' button is available to change your information.

It's important to keep your email address up to date, or you may have trouble accessing the system in future.
It's also important to keep your postcode up to date, as your entitlement to access may be checked based in part on that.
Your entitlement may also be checked against your membership number of your club - that isn't likely to change, but do make sure it is accurate.
