It occurs to me that sooner or later especially as BBO is a free site that pranksters will decide it is fun to sign up and sit at a table just to disrupt play [by stupid bids or even not biding] just 'for a laugh'. I wonder is any plan in place to overcome this possible scenario, a couple of solutions come to mind:firstly, that registration is not free, maybe a one of fee or even an annual fee: secondly, that registration requires an email address to which is sent a password so that miscreants could be traced and banned. At the moment presumably the most the site could do is ban a nickname, delaying the prankster by a couple of minutes whilst he/she opens a new account and resumes their fun. Woodman
