When the new forum was launched, the requirement to update your profile with your membership number and name as on your permit was stated on this website. This is a club policy because the forum is for members only, and those details enable bona fide members to be verified. Over the last few days the policy has been enforced and all accounts without those details have been disabled.
If you are a user of the forum all you need to do is to email the admin on the enquiries page, select the webmaster and state you want your account enabled. Make sure you include the forum username, your name (as on your permit) and your membership number. It will then be restored in a couple of days.
Thank you for your support in sharing club information with only our members.
