There have been a few instances recently of competitors signing on, or attempting to sign on, at competitive events without having up-to-date membership of the club. This is unfair on the vast majority members who pay on time (or at least before competing), and more importantly could invalidate the club insurance.
To the small minority of sinners (you know who you are!), I would remind you that you may not sign-on at any competitive event without being a paid up member. If you find at an event that your card is out of date, you can pay on the day. However, this should be kept to a minimum, as it slows down sign on, and occasionally forms go astray.
Please try to plan ahead.
