This will be due soon and the Club decided at its AGM in September to dis-affiliate from the EBU for the coming year.  This means if you take no action, you will be ineligible for any new EBU competitions.
Paper Master Points will cease to be issued after April 1st; if you have any you wish to be registered, send them to Aylesbury ASAP.
If you are not a member of the EBU and do not intend to be one, you need do nothing.
If you wish to become or continue membership you can either join one of the local affiliated clubs or register individually with the EBU and complete the Direct Debit mandate on page 27 of the February issue of English Bridge magazine.
In either case, your membership of Stone Bridge Club is unaffected.
