We do not have financial help from the RYA or sponsorship from any other Sailing organisation. So if you use our  'contribution to the sport' or just agree with our attempts to promote 'fair play' then please click on the Donate link/button and use PayPal to make a payment of just say a few £s each which would help us fund this work and website in the future.
A handicap request from a club or an individual will be prioritised in value order on our 'to do list, whether the donation is made before or after a completed request form is sent.  We do process and respond to all forms with proper and complete information, it's just that free handicap responses have to wait until we have some free time.  Priority treatment means an email response normally in days/week or so dependent on value submitted. Please remember that sending an email to progress a free handicap request just 'soaks up' our free time, a donation of just a few £s will prompt us to locate an earlier request form using your email address - even after some weeks, this is the only effective method of expediting a calculation request in our 'free queue'.    
PayPal is very secure, if you have any doubts then please use this link to refer to the PayPal site, but then we hope you will be convinced and return to click on the above Donate link/button graphic.
